Incident Details
A glider, with a certified flight instructor (CFI) and a student on board, was returning to the airport after approximately 45 minutes of flying in thermals. The instructor reported that they approached the initial approach point at about 1,000 feet for a landing on Runway 30. The glider passed over the end of the runway at an altitude of approximately 150 feet above ground level (AGL) and a speed of around 50 miles per hour.
Sequence of Events
After crossing the runway end, the glider encountered excessive lift. The pilot deployed spoilers and brakes to reduce lift, but these measures proved ineffective. As the glider continued its landing descent, a large sink rate developed. The aircraft subsequently contacted the ground, resulting in a hard landing.
Damage
The impact broke the glider's skid and caused a flat tire. No other damage was reported in the source. The source does not mention any injuries to the occupants or any further damage to the aircraft.
