Pretty easy to get it wrong in your light aircraft, and have a nasty encounter.
British glider over France. Parachutists DROPPING THROUGH CLOUD!
One hits the glider, knocks the glider wing off....both glider pilots then take to their chutes, one of which opened about 10 feet AGL...felt like it, anyway, he testified at the French Magistrates court....where they were held to be negligent flying a glider in open airspace...under a cloud!
And I got in trouble in a comp, following another glider near a known site, warned at the briefing....still got it wrong, and went round the parachute site on the UPWIND side. I never saw anybody, but the chief parachute instructor was freefalling, saw me below, maneuvered behind me, got my tail number and called the gliding competition director. I was basted in his office and before the entire congregation the next day.
So its easy enough not to understand the requirements of this strange form of aviation. Well done all those New Zealanders who managed to exit their jump plane in time. Meat bombing, we calls it over here.....
