Also don't join the fighter screen at the first sign of the Imps. You'll be taking on to much heat way to soon. Wait until they saw you should join the fighter screen. You'll be alright from there.
Actually K_K one time I DID save dad's ship (It was my first time doing it non the less). I haven't been able to repeat that fet of all the times I've replayed XWA.
If you leap before you look, I'm not catching you sorry ass!
