Got these from Dogma's website video's of several Onyxia battles. They did get her to 65% last night and she started to fly! will update this once that video has been posted.

Onyxia Flys! (http://webperso.easyconnect.fr/triex/onyxia_air.wmv)

Saw a bunch of screenshots of this raid on the WoW forums too - amazing stuff. She says something like "I'm bored of this, I'll just roast you from above" and takes off - it's wild!
