Cool glitch. You mentioned you want a floating vehicle battle though? You can make it happen in Forge, even if not as a regular gametype. Since Forge keeps track of kills it works as a fight. All you need to do is some teamwork. Get a Monitor to hold up a ground vehicle and have a Spartan or Elite man it. The Monitor takes care of turning, moving, flying around, etc. The Spartan or Elite will take care of, well, shooting. Get four players and you can have a 1v1. It's especially funny with Wraiths because that'll demand great teamwork between Monitor and vehicle operator. I've actually done this once, it can be fun if you're in the mood for a bit of absurdity.
