Wake turbulence encounter. On 26 September 2009, a privately operated Piper PA28-140 with only the pilot on board was about to touch down on Runway 26 at Humberside Airport, North Lincolnshire UK after a day VMC approach when the aircraft rolled uncontrollably to the right in the flare and struck the ground. The aircraft came to rest inverted beside the runway and suffered significant damage but there was no fire. The pilot sustained serious injuries.
