The Power of Positive Lightning
At 1609 hours a fearsome force suddenly and violently shredded large sections of the glider. The instructor later recalled a “very loud bang” and a distressingly “draughty” cockpit. Dazed and briefly unconscious, he realised that “something was seriously amiss... requiring unpleasant and decisive action.”
By the time he vacated the wreckage--noting on his way out that there was no need to eject the canopy, nor any canopy--his student had arrived at the same conclusion. Witnesses on the ground observed a bright flash and heard a loud crack, and craned their necks to see a ball of smoke and fine debris hanging in the space where the glider had been. Below this, the remnant of a fuselage plummeted earthwards at high speed, with larger sailplane fragments fluttering behind. Thankfully two open parachutes were among them, with deafened and soot-blackened aviators swinging underneath. They were the fortunate survivors of a curious and powerful phenomenon known as positive lightning.
