Funny you should mention that... the propeller got destroyed during the first dress rehersal last Monday. One of the parents helping backstage backed into it. Then... well, it JUST fit through that door, and on that first dress rehersal, the stage hands didn't QUITE have the plane lined up right...
I offered to loan them my roll of duct tape. I was turned down. (Don't they know that duct tape fixes EVERYTHING? It's one of the building blocks of the Universe!)
Fortunately, the propeller got rebuilt during the week...
