Swift S-1 stalls in low-level final turn during air-show display

The pilot of a Swift S-1 was seriously injured in a stall and departure from controlled flight in a low-level final turn during an air-show display at Shoreham; aircraft substantially damaged. After a roll-on-tow sequence the pilot released at ~157 km/h and turned 180° right to land downwind at the launch point. Realising he would overshoot, he extended airbrakes, then began a 180° left turn at ~12 m AGL with 50–60° bank. Airspeed went unscanned for the last 8 seconds and decayed below the in-turn stall margin; the left wing dropped and the glider struck the runway. Display pressure to land precisely had eroded normal safety margins.

1. Air-show display, glider on tug: A Swift S-1 aerobatic glider flew in an air-show display team at Shoreham Airfield; low cloud (base ~500 ft) limited the team to a low-level profile.
2. Display pressure; abnormal as normal: The display required landing precisely at the launch point to minimise turnaround; the pilot later felt he had grown used to lower margins than normal — 'the abnormal had become normal'.
3. Release low, downwind of launch point: After slack developed in the tow rope, the pilot released below the cloud base and turned right 180° to land downwind, without assessing height and speed for a safe approach.
4. Stall in 180° final turn at ~12 m AGL: Realising he would overshoot, the pilot began a steep left turn near the ground; without scanning the ASI, airspeed decayed below the stall margin and the left wing dropped.
5. Wing-drop impact on runway: The left wingtip struck the runway followed by the nose, rolling the aircraft left nose-down; the pilot extracted himself with back injuries, aircraft substantially damaged.
