DailyDirt: Flying Faster Than The Speed Of Sound
from the urls-we-dig-up dept
Supersonic flights haven’t been available to the public since the Concorde (and the lesser known Tupolev Tu-144) stopped flying. The economic reality of flying faster than the speed of sound doesn’t look too profitable, but maybe someday an airline will figure out a way to do it (and do it safely AND quietly). Or maybe we should just look forward to riding trains inside evacuated tubes.
- NASA is looking to design “low boom” (aka quieter) supersonic planes. The Quiet SuperSonic Technology (QueSST) project will be just the first part in a series of ‘X-planes’ for NASA’s New Aviation Horizons initiative. [url]
- A hypersonic cargo plane has been patented by Airbus — with claims to reach Mach 4.5 (much faster than a Concorde at Mach 2). To reduce the sonic boom, the plane has a rocket engine to boost it nearly vertically so that the sonic boom would dissipate in the upper atmosphere — and turbojets and ramjets would provide horizontal thrusts at appropriate altitudes. [url]
- If you were thinking it’d be great to ride in a hypersonic plane with a broadband wireless connection, you might have to solve the communication blackout problem that comes with superfast vehicles traveling through the atmosphere. If an ionized plasma forms around your hypersonic plane (usually at around 5 times the speed of sound), you might be able to get around it with some special signal processing equipment. [url]

DailyDirt: Flying Faster Than The Speed Of Sound (Again)
from the urls-we-dig-up dept
The Concorde jet flew for nearly 30 years before it went out of service. And now, the time airline passengers spend in security lines wastes far more time than a supersonic jet could make up in the air (depending on the journey, of course). Still, traveling fast is cool, regardless if it’s done by air or in an evacuated tube — as long as it’s fast. Perhaps there’s some analogy to the Skyscraper Index where supersonic transportation designs arise right before an economic recession… so maybe hold off on buying a high-speed ticket to London.
- Airbus has a supersonic jet design that could take passengers from NYC to London in 1 hour. This plane would takeoff vertically and then travel at up to 4.5 times the speed of sound. It would be faster than the Concorde, but it would only carry 20 passengers at a time. (It will also probably never be built.) [url]
- China’s first scramjet engine has been tested, making it the second nation (after the US) to develop a scramjet engine for sustained atmospheric hypersonic flight. These supersonic planes are meant for military operations, but it’s unclear if these designs will have a practical use. [url]
- Refurbished Concorde jets could be flying again in 2019. Don’t get your hopes up just yet, though. There have been previous (failed) attempts to bring the Concorde back into service. [url]

Sen. Wyden Introduces Bill Aimed At Limiting FBI, US Marshals' Flying Spy Planes
from the hacking-away-at-the-surveillance-overgrowth dept
It’s safe to say no domestic surveillance program will be escaping legislators’ attention in the post-Snowden era — at least not for the forseeable future. It’s only been a couple of weeks since news of the FBI’s secret spy plane fleet made national headlines and there’s already legislation in the works aimed at setting some… um… ground rules.
In a bill announced Wednesday, Wyden joins Nevada Republican Sen. Dean Heller on the Protecting Individuals From Mass Aerial Surveillance Act, which if passed would require warrants for the government to analyze and collect data gathered en masse via domestic airplane or surveillance drone.
“Technology has made it possible to conduct round-the-clock aerial surveillance. The law needs to keep up,” Wyden said in a statement. “Clear rules for when and how the federal government can watch Americans from the sky will provide critical certainty for the government, and help the unmanned aircraft industry reach its potential as an economic powerhouse in Oregon and the United States.”
It’s not just the FBI’s flying spies being targeted by this bill. It’s also looking to dial back the US Marshals Service’s use of airborne IMSI catchers, a.k.a. “dirtboxes,” as well as targeting surveillance drones, picking up where 2013’s stalled Drone Privacy Act left off.
Hopefully, the bill will force a bit more transparency about use of these surveillance techniques. A warrant requirement is a nice thought, although it’s hard to imagine what sort of warrant would cover a “search” that involves flying a plane in continuous circles over a small area of a city.
Considering the lowered expectation of privacy in public areas, the warrant requirement is going to be a tough sell. If it does stick, it will at least ensure deployments are targeted, rather than just exploratory. There’s an opportunity here to force better and more detailed reporting of deployments, as well as significantly limiting the use of flying surveillance vehicles by eliminating exploitable loopholes.
The bill also would prevent government agencies from running footage obtained by drones or planes through facial/pattern recognition software in hopes of stumbling across untargeted suspects. It also would forbid law enforcement agencies from bypassing restrictions and reporting requirements by hiring private contractors to perform their illegal surveillance for them.
Five years ago, this sort of legislation would be dead on arrival, with deferential nods to terrorism and the War on Drugs replacing any serious consideration of the public’s privacy. Thanks to the Snowden’s leaks, any bill seeking to limit domestic surveillance now has a fighting chance, with even the reluctant administration forced to make more concessions to privacy than it would under other circumstances.

DailyDirt: Flying With The Greatest Of Ease
from the urls-we-dig-up dept
Airplanes have been commonplace for quite some time now, and we’ve grown accustomed to what an airplane should look like. Ask any kid to draw a plane, and you’ll probably get familiar results. However, this doesn’t mean we’ve reached the end of novel plane designs. Plenty of unconventional planes are being designed and tested, and here are just a few.
- NASA is testing an experimental wing design with 18 electric motors as part of its Leading Edge Asynchronous Propeller Technology (LEAPTech) project. Each motor can be optimized for better ride quality and noise reduction — and possibly improved fuel consumption. [url]
- The Russian PAK TA concept is a supersonic transport that could be ready for military service by 2024. A 200-ton capacity plane traveling at 1200 mph with a range of 4,000 miles sounds a bit futuristic because it would be amazing to see a plane actually capable of doing it (but maybe not so amazing in another 10 years or so). [url]
- DARPA wants to make a VTOL (Vertical Take-Off and Landing) aircraft that’s much much better than a helicopter or existing VTOL designs. Boeing has a Phantom Swift design that’s been built (as a 17% scale model) — one of four contenders aiming to meet DARPA’s technical specs. [url]

Feds Put Fake Cell Towers On Planes, Spied On Tons Of Innocent Americans
from the because-surveillance-is-fun,-yo dept
The Wall Street Journal broke the news that the DOJ has been spying on tons of innocent Americans by putting fake mobile phone towers on airplanes and scooping up all sorts of data from people who thought they were connecting to regular mobile phone towers.
The U.S. Marshals Service program, which became fully functional around 2007, operates Cessna aircraft from at least five metropolitan-area airports, with a flying range covering most of the U.S. population, according to people familiar with the program.
Planes are equipped with devices?some known as ?dirtboxes? to law-enforcement officials because of the initials of the Boeing Co. unit that produces them?which mimic cell towers of large telecommunications firms and trick cellphones into reporting their unique registration information.
The technology in the two-foot-square device enables investigators to scoop data from tens of thousands of cellphones in a single flight, collecting their identifying information and general location, these people said.
We have, of course, reported for a while now on so-called Stingray devices, which mimic mobile phone towers on the ground (and have noted that Stingray is just one brand of a few such devices, known as IMSI catchers), but putting them on special planes and flying them around would allow law enforcement agencies to get a lot more information on a lot more people. Given that law enforcement efforts like this are supposed to be narrowly targeted towards those actually suspected of breaking the law, this seems like a massive 4th Amendment abuse, creating mass surveillance programs for law enforcement with little real oversight or control.
While it may not be entirely surprising that this is happening, it is yet another surveillance program being done with zero public transparency, zero public debate and zero public input. That’s a huge concern as we’ve seen time and time again how such programs get abused.
And, while the WSJ doesn’t come out and say it, it certainly sounds like it got this info from a concerned whistleblower inside the US Marshals Service:
Within the Marshals Service, some have questioned the legality of such operations and the internal safeguards, these people said. They say scooping up of large volumes of information, even for a short period, may not be properly understood by judges who approve requests for the government to locate a suspect?s phone.
Some within the agency also question whether people scanning cellphone signals are doing enough to minimize intrusions into the phone system of other citizens, and if there are effective procedures in place to safeguard the handling of that data.
As such programs keep getting disclosed, think of how many such other programs there are that we just don’t know about?

DailyDirt: Waiting In Line Isn't Fun
from the urls-we-dig-up dept
Queuing theory is a subset of applied math that looks into the behavior of waiting in line and algorithms that optimize various aspects of this particular kind of resource allocation. Retailers of all kinds are interested in this kind of math because it can improve customer satisfaction and get more products out the door. Apple reduces long cashier lines with employees who can accept payments anywhere in its stores. Fry’s Electronics has the giant single line that feeds into a massive array of cashiers (aka the serpentine line). There are self-checkout lanes at the grocery store, but there’s no silver bullet to eliminate waiting in lines. Here are just a few more links on this problem of civilization.
- Ever pick a checkout line at the grocery store and think “I always pick the slowest lane” once you’ve committed to a particular cashier? The math says that the odds of picking the fastest lane are against you, so you’re most likely right that you never pick the fastest line. [url]
- Waiting in line at Disney can be cut short with its Fastpass system, but what does Fastpass really optimize? FYI, Disney doesn’t let you hire disabled kids to cut in line anymore. [url]
- The best system for boarding planes is not the one that most airlines use, but Southwest’s boarding method does pretty well. A few studies have looked at how to board planes more efficiently, but the Jason Steffen method isn’t used by any airline (and there’s little incentive for most airlines to change what they’re currently doing).

DailyDirt: Aircraft That Stay In The Sky For Days (Or Longer)
from the urls-we-dig-up dept
Most folks don’t really like flying for more than a few hours at a time, so it’s not really a problem for a lot of people that most planes aren’t even capable of flights lasting longer than day. (Zeppelins can fly for weeks at a time, but those ships haven’t been flying regularly for a while.) Autonomous drones have been making some really long flights recently, and there may be more uses for aircraft that can stay up in the air for long periods of time. Here are just a few examples.
- Google has acquired Titan Aerospace for its solar-powered drone technology that can act as “atmospheric satellites” by flying for months or even years at a time. Google presumably outbid Facebook for this company, but regardless who bought this company, it sounds like wireless internet services could become more competitive with traditional wireline telcos/cablecos. Maybe. [url]
- The world’s longest aircraft, the Airlander, is just over 300 feet long and can fly for a couple weeks. This particular Hybrid Air Vehicle (HAV) is a cross between a blimp and a zeppelin — and a bigger version is designed to carry a 50-ton payload. [url]
- The Solar impulse 2 has a maximum speed of only about 85 mph, so it’ll take more than a couple days to accomplish its flightplan to circumnavigate the globe. This solar-powered plane is expected to launch sometime in mid-2015, and it’ll take a solo pilot almost a week to travel around the world. [url]

Pilots Want To Know Why The DHS/CBP Are Searching Their Planes Without Warrants
from the warrants-are-becoming-nothing-more-than-a-fond-memory dept
Government agencies continue to operate under the assumption that warrants, reasonable suspicion and the like are luxuries that our nation can no longer afford, not while we’re under constant attack by terrorists and drug smugglers.
The AOPA (Aircraft Owners and Pilots Association) is reporting an increase in DHS/CBP (Border Patrol) searches of small aircraft, including planes that never left the country.
With a growing number of reports from law-abiding pilots stopped by armed federal agents on the ramp, their aircraft searched by federal agents, the U.S. Department of Homeland Security Customs and Border Protection remains silent, and outrage is building.
AOPA is questioning CBP’s authority to conduct the searches, and demanding a response from officials at the highest level. There has been no meaningful response to date from CBP to Freedom of Information Act requests filed months ago by AOPA and affected pilots.
The FOIA requests filed by AOPA date back to February 12th. The CBP told the association not to expect a response until August 12th, at the earliest. The AOPA has given the CBP until July 20th to produce the requested documents or it will be taking its case to court, as well as “advising Congress and congressional committees” about the unexcused delays.
One of the FOIA requests seeks information on the warrantless search of pilot Gabriel Silverstein’s plane, which occurred on May 5th. Silverstein’s plane was actually searched twice by federal agents. The first search was more perfunctory, with DHS agents replacing the normal FAA agents during a routine ramp check. The second, however, was much more intrusive.
[A] fuel stop, one of many made during a business trip from New Jersey to California and back in the Cirrus SR22 that Silverstein shares ownership of, proved much more troubling: Federal agents called out the dog.
A search lasting more than two hours produced nothing incriminating. Silverstein was free to go, but he and his husband of nine years, Angel, were on their own to re-pack luggage, the contents of which had been emptied along with the rest of what could be removed from inside the aircraft. Though more needs to be learned to understand the true legality, or constitutionality, of that search, agents told Silverstein he had no choice.
Although the agents involved identified themselves as only “homeland security,” Silverstein recognized their uniforms’ insignia to be that of Customs and Border Protection. (He also received a business card from one of them which identified that particular agent as CBP.) So, what are CBP agents doing searching a plane in Iowa City, miles from any international border? Silverstein had a registered IFR flight plan, which had received clearance at every stop, detailing every leg of his flight up to that point — a flight that saw him travel from New Jersey to California (and part of the way back) with various stops for fuel, all without leaving US airspace.
The DHS knows but it’s not saying, at least not yet. (Any sobering findings will presumably be heavily redacted.) But judging from the agents’ conversations with Silverstein, it would appear they believed he was smuggling drugs.
Silverstein said the agents in Iowa City urged him to confess to possessing a small amount of marijuana, suggesting such a confession could cut the whole process short. (Silverstein told AOPA he is a teetotaler, and never indulges much less possesses marijuana, nor did he have any reason to believe others had put marijuana in the aircraft.) Silverstein said agents told him they believed marijuana should be legal, but they had to enforce federal law.
Searching a plane without a warrant and finding nothing is not enforcing federal law, no matter how the agent playing “good cop” attempted to portray it. Encouraging a person to falsely incriminate himself is not enforcing federal law, no matter how much the agents would have preferred to be back by quitting time. But on top of this dubious definition of “enforcement” lies an even more dubious definition of “reasonable suspicion.”
He said the agents “clearly suggested” they were interested in his aircraft because he had stopped in Colorado, a state that recently legalized possession of small amounts of marijuana.
If you think that logic is weak, there’s more. The Atlantic details a couple more episodes of DHS/CBP agents vs. private plane pilots/owners. Larry Gaines, flew out of California, landing at a small, rural airstrip in Oklahoma. He was headed to dinner with a friend when he realized he had left his eyeglass case back at the airport. He returned to retrieve it and was greeted by local law enforcement who prevented him from returning to his plane and informed him the DHS was on the way. From Gaines’ account of the event:
2 black Suburbans drove up at some point during this time, plus more Cordell Police and Washita County Sheriffs. All told, there were 3 police cars, 3 sheriff’s cars, and 2 Suburbans with black windows from what I was later told was DEA. The officers/agents in the Suburbans were dressed in what appeared to be riot gear – body armor and helmets, I believe. They had shotguns and at least one German Shepherd dog. One of the local sheriffs was definitely in full SWAT regalia. It was over 100 degrees F. I counted 20 officers, deputies, and agents. Seven were dressed & equipped, literally, for armed conflict…
A large business jet arrived and circled overhead for the next 60-90 minutes. A King Air 200 [a sizable twin-engine turboprop plane] arrived and landed. 2 Border Patrol agents got out.
That’s a lot of “response” for a pilot with a clean criminal record. The agents on the scene were unable to explain their actions with anything more specific than Gaines’ flight fit a “suspicious profile.” Gaines asked for details about the “profile” and received this in reply: “You started in California and flew west to east.”
This almost sounds made up on the spot. After all, flying out of California doesn’t present many options for a pilot who wishes to remain in the Continental US, but still leave the state. But if Gaines fits the “profile” by flying west to east, how does Silverstein fit in? Sure, he left California traveling east before his run-in with federal agents, but it was part of a return flight to New Jersey, which started east to west.
The common thread seems to be drugs. An agent pointedly asked Gaines, “There’s a lot of drugs in Stockton, isn’t there?” (This despite the fact that Gaines’ flight originated in Calaveras. His plane is registered in Stockton.) Silverstein flew west to east, returning to New Jersey, with a stop in Marijuana, CO.
Both pilots returned to their planes to find law enforcement waiting for them. Silverstein found the search to be already underway by the time he got to his plane. Gaines was greeted by local cops, which soon swelled into a small army. Gaines, however, refused to let the agents search his plane without a warrant. The agents backed down only when he agreed to allowing a drug-sniffing dog to walk his plane.
Under what authority these combined forces are searching planes without a warrant is unclear. The DEA would seem to be the most interested party if it’s indeed drugs these agents are looking for. But these two episodes show the DHS/CBP clearly is taking the lead. The latter two agencies aren’t too concerned about warrants or constitutional rights, seeing as the so-called “Constitution-free zone” is still in effect and the DHS has already gone on record as regarding Fourth Amendment rights to be an impediment to innate pureness of an agent’s “hunches” or “intuition.” But in these cases, along with nearly a dozen others, the pilots involved have never crossed a border, breached restricted airspace or otherwise done anything illegal.
It almost appears as though these agencies would prefer private pilots travel like everyone else: routed through TSA agents and safely aboard FAA-tracked airliners. So much for being able to move freely around the country. Traveling within our borders now seems to be as suspicious as making domestic phone calls.

DailyDirt: Weapons In The Sky
from the urls-we-dig-up dept
Completely autonomous drones that can decide who or what to strike are still many years away from becoming a reality, but the military has already developed various unmanned aircraft that it’s been using primarily for gathering intelligence (rather than for attacking targets). Here are a few more examples of some of the high-tech flying weapons that exist today.
- The $1.8 billion prototype Unmanned Combat Air System demonstrator was recently launched into the air from a catapult. This marked the first-ever catapult launch of a drone from the flight deck of an aircraft carrier. [url]
- The Lockheed Martin F-22 Raptor, the most advanced stealth fighter jet in history, seems to have a problem with suffocating its pilots during normal flight. Since 2008, pilots would frequently and inexplicably suffer from what appeared to hypoxia — in one case, a pilot hit a tree while landing and didn’t even realize it. The cause of the problem was only recently identified as being due to a faulty valve on the pilots’ life-support vest. You’d think that after spending almost $80 billion on these planes, it wouldn’t have taken them almost five years to figure this out. [url]
- After 16 years and billions of dollars, the “Airborne Laser” project — a 747 jumbo-jet equipped with a powerful laser that can shoot missiles out of the sky — has finally been scrapped. Cost prohibitive and impractical, the Airborne Laser would likely have cost $92,000/hour to fly if it had worked. [url]

DailyDirt: Cool New Planes
from the urls-we-dig-up dept
Futuristic-looking jet planes used to inspire all kinds of technology geeks, back when commercial flying was a relatively new venture. Over the years, though, the airline industry has matured quite a bit, and commercial plane designs don’t really look that unique anymore. But that doesn’t mean engineers aren’t coming up with novel plane designs. Here are a few cool new planes that could take to the skies in the not too distant future.
- Supersonic planes have a problem of creating a “sonic boom” when they travel faster than the speed of sound, causing all kinds of headaches for commercial and military operations. A new biplane design with twin wings would have a much reduced sonic boom, as each wing could cancel out the effects of the other (at least in theory & simulations). [url]
- NASA is interested in liquified natural gas (LNG) propulsion for creating super fuel efficient airplanes. Planes fueled by LNG won’t be ready for at least three generations of airplane technologies (aka N+3 airliners), so don’t expect to see any before 2030. [url]
- The first production aircraft to completely satisfy FAA spin resistance standards will likely improve the safety of non-commercial general aviation. Icon Aircraft’s A5 amphibious light sport aircraft is a two-seater plane design that greatly reduces the plane’s potential to stall out or go into an uncontrollable spin. [url]
