Christ oh Mighty, if you can believe in ships that not only perform impossible manouevers in space but also make a lot of sound at the same time (point being - no sound in space) then is it beyond the realms of possibility that maybe the Force (the thing that makes those Jedi able to do all that other stuff that's impossible) made Leia remember her mum? It really isn't that hard to imagine, but people need this sort of thing spoon fed to them these days. No imagination.
