The co-pilot who was pilot flying, then lowered the nose wheel onto the runway for a firm touchdown to ensure continued contact due to the crosswind conditions. It appeared that the aircraft's crown skin was buckled with damage noticeable between Station 610 and 632. The accident happened in daylight VMC with wind from 340deg at 9 kts.
