During the second flight of the day (using a longer towline intended to alleviate the turbulence), the test pilot encountered severe buffeting problems and he had to cast off at low altitude. The flight ended catastrophically when Brooke-Smith attempted to side-slip out of the wake and struck the ground "nose-down" at 90 mph, injuring himself seriously and heavily damaging the aircraft.
During the second flight of the day (utilizing a longer towline to reduce turbulence), the test pilot encountered severe turbulence problems. The pilot was forced to make an emergency landing at low altitude due to the difficulties. Unfortunately, the aircraft crashed "nose-down" at 90 mph while attempting to exit the wake, resulting in serious injuries and significant damage.
