Red Baron has got to be the hardest mission in the game.. everything else is a 1st or 2nd try success for me. Worst part about the red baron is when I finally manage to nail all the vans with a little bit of fuel left- NOW I GOTTA FLY ALL THE WAY BACK. Great. Also, you can steer on the ground you just gotta tap the drive/reverse when doing so, just like the cars. It's too hard to shoot and fly at the same time with that damn thing wobbling through the air so I just land it, aim it and unload..
