The last data point captured by the flight data recorder on Roy Halliday’s Icon A5 before his fatal crash shows the light sport at 200 feet above the water with a speed of 87 knots, says the NTSB. The preliminary report says a witness told investigators that “he saw the airplane perform a climb to between 300 and 500 feet on a southerly heading and then turn and descend on an easterly heading about a 45° nose-down attitude. He then saw the airplane impact the water and nose over.”
