Aquaplaning may reduce the effectiveness of wheel braking in aircraft on landing or aborting a takeoff, when it can cause the aircraft to run off the end of the runway. Aquaplaning was a factor in an accident to Qantas Flight 1 when it ran off the end of the runway in Bangkok in 1999 during heavy rain. Aircraft which can employ reverse thrust braking have the advantage over road vehicles in such situations, as this type of braking is not affected by aquaplaning, but it requires a considerable distance to operate as it is not as effective as wheel braking on a dry runway.
