Somebody was where they were not supposed to be or the JFK Port Authority just saw their last A380 operation. Bottom line though, the Management of US airlines have become transfixed with outsourcing of jobs and routes to the Replacement Jets (RJ's) and it must stop. JFK is an International airport meant for International airplanes not RJ'S. They will likely find fault with the RJ for not proceeding to his gate or for not completely clearing the taxiway. This will be done because of politics and not facts. Just like Air France blamed a part off a CAL DC-10 caused their ill fated Concorde to crash. They didn't follow their own procedures but in cases like this facts don't matter when deep pockets are involved. Just sayin
