"The AOTC speeder is a real prop on fire"
WHAT!?!??!?!
It can't be!! It's the worst CGI in the film! Where is the evidence you've seen that this was a real shot? (The evidence of my own eyes says different) I can't remember seeing it in any behind-the-scenes featurettes. I know a physical prop was used for most of the sequence but not the actual crash!
If you are right, I would eat my hat (If I owned a hat)! Then get my eyes tested and have a CT scan on my brain!
Plus that is not fire, mankind has had the invention of fire for quite a while and it has never looked like that!
