I hate to explain a joke, but this one is really really obscure if you don't realise the fact that Jets run on air and that the vacuume of space has no air for the Jet to run on... I guess I just explained the joke.

Jets have impressive structural integrity, spending such an arbitrarily long time in outer space with utterly exposed components... but on this site, you could inflate a Jet by shoving random furries up its tubes without any regard for anyones safety and everything is still alive!

Anyway, long submission text is long, either way, there is a reason this is in the scraps.
