Analysis

The falcon 10 touched down long and fst on a wet runway, experienced hydroplanning and went off the end of the runway,struck a drainage ditch and collapsed the landing gear. The nose gear came back and bent the throttle quadrant bracket, pulled the fuel controls to 90 percent power. This pushed the aircraft on its belly another 1000'-1600' until it came to a stop on a hillside.
