Is Reggie Bush Blast Off TD against Mia

Seeing as the only one that come to mind nearly as athletic is Mike Vick somehow keeping off the ground when he dove in from the 4 yard line from like 4 inches from the ground.

I remember that play. I've always thought it was not a TD because I thought his knees touched the ground before crossing the goal-line. It was a nice play but not close to the Blast Off.
