On 22 December 2007, two gliders were winch-launched at approximately 1140Z from Goldfields Gliding Club at Hennenman in the Free State. After they were launched, they headed in a south-westerly direction along the railway line to Virginia. After soaring in the same two thermals, they then separated overhead Virginia. The pilot of ZS-GND turned due east at Virginia and then headed in a north-easterly direction of 030s? towards Ventersburg, east of Hennenman. According to the pilot of the second glider, the pilot of ZS-GND notified him some time later that he was soaring overhead Ventersburg, and was heading towards Kroonstad in a northerly direction. The pilot of ZS-GND later informed the second glider pilot that he was soaring overhead the Goldfields Gliding Club at Hennenman Aerodrome and that he was just flying around in the area. There was no further communication between the two glider pilots after this last conversation. According to the GPS trace, Cambridge logger that was fitted to the glider, at approximately 13:13:46Z, ZS-GND passed 2.5 km to the north of the Goldfields Gliding Club on a heading of 210s? at an altitude of 2 621 ft, with the speed and the descent rate increasing. When the glider was at the top of the loop, the glider exited to the left in a barrel-type manoeuvre at an altitude of 2 538 ft (at 13:13:58Z). Although there was no eye-witness to the accident, a tractor driver indicted that he heard the sound of the glider breaking up in the air. Debris from the glider was found spread in a wide area, with the main wreckage in a ploughed maize field approximately 3 km south-west of Hennenman aerodrome. The glider was destroyed during the accident sequence. The glider pilot sustained fatal injuries in the accident. PROBABLE CAUSE: All evidence from the wreckage recovery suggests that high speed was experienced, causing flutter and a resultant structural break-up due to excessive g loading.
