It takes longer now. In the challenge I ran on the other forum it went for 21 missions and none of the survivors got a promotion. In previous challenges in earlier iterations of the game they would have gotten one. Give it some more time!
Got it HARD like everything else in this game!
I even had the Engine Crap out and put the plane in a fence.
Got me 23 days in the hospital.
Another time I died using 4 times speed in game trying to fly with a broken bird.
I crashed but so did the game and thus this guy lived.
