If there was any precipitation on the 'dumb-bell', then the nosewheel steering could have been ineffective, especially if a burst of power was used. I have been on a 747 that carried straight on with the nose wheel fully cocked, due to the slippery surface (water on paint).
As to those who seek to blame the airport/government or the VS crew, consider this :- 747's have been operating into and out of Antigua safely, since the 70's. Was anyone injured/killed as a result of this excursion?
I expect a little time in the simulator, practising turning, will be the only action required.
