Some of the durations provided on this site are historically correct but not correct according to BARIS. If you answer wrong twice all your rockets will blow up. I think I've found the right answers--for instance the duration for Musa Manarov (page 105) is historically 541 but according to BARIS the correct answer is 366 (probably b/c BARIS was using old info--Manarov's first mission was 366 days long, but he went on another in 1991). Anyway, I found it annoying enough to keep googling until I found something--I hope they're right.
