I would have thought FAA, the airport authority and the mayor of MIA would all be in direct contact with Qatar ASAP and be DEMANDING an explanation as to how some of their property was damaged, and sending a repair bill. From the FAA's point of view it would be from a safety perspective to prevent any other 'pilot' making the same error. It may be that american TV does not have the same clout, contrary to their own beliefs, but the FAA could ban Qatar from US airspace if they refuse to answer and give a full and open explanation tout suite. After all they have the crew to ask what happened. I'm sure Qatar would have held a tea no biscuits meeting once the engineers had grounded the a/c and a replacement required. Has it been fixed yet?
