right version
guys i actually talked to the crew that was involved, the real story is the tug and tow bar were removed, after start checks done an left area was side was clear, as the tug was goin away from the ac towards the rear the towbar came away from the tug as the pin they had used was to short to hold the tow bar in it rolled back and got caught in front of the wheel as they were taxing out... think it was tower who stopped them.. another thumbs up for service air
