My plan on 1945; The zeppilin can hit you anywhere except from directly behind it, unless you get really close. Send your 4 planes to teh observers, 2 on each side to take them down in the first few turns. After that, get your planes far away from the zeppilin so they won't be shot. You have the space to move and the zeppilin won't be speedin. Get your planes behindthe zeppilin, and send in one at a time to hit the rear end. Do a 180 before you reach directly behind it so it won't shoot back. I kept the rest of the planes in case I made a mistake, and sometimes I sent them all in if I could avoid friendly fire. I made it with 3 planes almost full and 1 plane almost dead(2 stars). Good luck!
Well, yes, normally if they mention it's a'red remover' Xpac it's normally going to be like Red Remover. Duh :P
Oh, if you don't like the annoying fart-fail noise, then stop failing! :P
For the piano chase: After trying many different ways of wheeling etc., I learned that you can just hold up the entire thing, as long as your accel and spped are maxed
