During one of the all-night engine runs a few days before First Flight, I was running the engines ... I looked over the side and saw a large puddle of hydraulic fluid... I asked what happened, and he said it must have been a loose B nut... We were all sleepy, so we went home and thought no more about it. !! wtf?! you're test piloting a mulit-million dollar jet plane, it starts leaking fluid when you're testing the engine on the ground, it leaks fluid, and since you're sleepy you just forget about it and go home?! That's pretty crazy. I guess these guys are more gung-ho than I thought. Would you even do that even if you were testing a race car?
