I'm sorry, padre. I didn;t mean to have to be the one who told you. Penance?

I am very pleased to have, in my modest collection of DVDs, a disk on which three of the Buck Rogers serials from the late 1930s have been edited together to form lengthy movies. In these, space ships are depicted. When in flight, smoke and sparks come out of the rocket end of the ships ... and the smoke goes out and up, while the sparks go out and down.

Next thing you know, zmjezhd is gonna be telling me that this is not how space ships work in real space, either. Is nothing sacred?
