There's a bug that's still in game I think where you can "superman" into the sky. IIRC you do something like jump into water (not run into it) then walk out of it... I think it takes a few goes to trigger and I may not be remembering how it works /actions involved exactly but it was something like that.
I think it's triggering the worm hole entry animation for some reason. There was also some weird thing where you get bent back wards... I have some screenshots somewhere of these things but maybe I could just try and show you some time.
