Well I can't resist such a silly task!
I gave the B17 a fair few runs around but never made it through - S-curve drilled me into the walls every time, well except one where I thought I almost had it but actually was skidding along the floor before BOOM!
262 was the same story, BUT the Yak-15 on extremely low power through the curve got through in 50 seconds! (after many tries stalling as I exited onto the final stretch!)
