1969 February 21 - . 09:18 GMT - . Launch Site: Baikonur. Launch Complex: Baikonur LC110R. LV Family: N1. Launch Vehicle: N-1 11A52. FAILURE: First stage failure.. Failed Stage: 1.

N1 3L launch - . Payload: Soyuz 7K-L1S s/n 3. Mass: 6,900 kg (15,200 lb). Nation: Russia. Related Persons: Afanasyev, Sergei, Dorofeyev, Kirillov, Mishin. Agency: RVSN. Program: Lunar L3.

N-1 serial number 3L was the first N-1 launched. The vehicle ran into trouble immediately at lift-off. A fire developed in the tail compartment. The engine monitoring system detected the fire, but then gave an incorrect signal, shutting down all engines at 68.7 seconds into the flight. British intelligence detected the launch attempt, but the CIA's technical means for some reason missed it and they denied for years that it had ever occurred. In retrospect the launch team at Baikonur pointed to a grave mistake - at the christening of the first N1, the champagne bottle broke against the crawler-transporter rather than the hull of the rocket. After the 3L failure everyone knew there was no chance at all of beating the Americans to the moon. Additional Details: here....
