This aeroplane was climbing out over Jamaica Bay within about 5 miles of JFK at the encounter. I would think they were going slower than 250kts! Whatever the distance of rudder travel, I am still bemused that any experienced pilot would use rudder as primary control in that circumstance, and how he assessed it. The fatal flaw was human technique and presumably training, not fin attachment. The A300 has been carrying the can quite unfairly.
