Congratulations on your baptism of fire and welcome to the club: we've all been there, done that!
You don't say how the wing caught fire. Was it sparks from the fuse? Andy Blackwell used to put a a bit of aluminium foil under the Jetex motor's nozzle which caught any stray sparks. It was of course removed before launch.
I hope restoration of the Skyjet is not too problematical .
