It looks like the pilot of that Atlas 747 simply was not paying attention. How in the HECK do you roll over a hold-short line and onto an active runway like that?? I hope those Atlas fly-boys lost their jobs over that one. Only God Himself, intervening personally, prevented a disaster that day.
God, Boeing, and the talented pilot in the 737 that managed to get his aircraft to stagger aloft early enough to clear the wayward 747.
I really doubt that an Airbus in normal flight law would allow the pilot to rotate early like that.
That's one possibility, but I don't know what clearance he had been given, do you?
Several runway incursion fatals have resulted from errors by controllers. Here are some examples from a few years ago. The Sarasota accident was particularly disturbing to me.
