The cosmonauts are also pressing for a meeting with Brezhnev to discuss planned military experiments, the role of the pilot in spacecraft, and the mistakes of OKB-1 in spacecraft design. Kamanin thinks this would be too risky - unforeseen results could occur. Titov is assigned to the Spiral spaceplane programme. Kamanin thinks the project is risky and likely to be cancelled. But Titov enjoys being able to fly high performance MiG-21 aircraft, and has wanted out of the main cosmonaut program for a long time. There is constant high level pressure on Kamanin to assign OKB-1 engineer cosmonaut candidates to crews and fly them.
