Stopping the plane:
Alright Martin and all,
No need to cheat friend !! Once youve got the hangar doors open turn around to face the plane and shoot your webbing (not web ball) continuously at one of the proppellers only. After a bit that propeller will stop turning causing the plane to go round in circles. At this point you can relax, the plane is not going to crash . All you have to do now is target the other propeller and shoot webbing at it until it stops. *Level Done!!
Good luck fellow gamer!!

ps *You will need to open the first 2 or 3 hangar doors and make sure you as far ahead as possible before attempting the propeller webbing. Just carry on through the hangars until you reach a door with no switch and you cannot go any further. Its at this point you should face the plane and start webbing the propeller causing the propeller to stop turning and forcing the plane to go round in circles. If you run out of webbing dont worry there should be some web cartridges nearby that reappear after a while, but just make sure you have enough webbing to stop the first propeller. If you are still having probs, let us know.
