Glider Stall Spin Video on YouTube
He sure looks like he is flying fast enough that a stall wouldn't have
occurred. Something break? http://www.youtube.com/watch?v=_xCct8cDtyk |

The airspeed would have been significantly lower. Perhaps a large wind gradient, too. Alastair |

He sure looks like he is flying fast enough that a stall wouldn't have
occurred. Something break? Look at the wind sock: There's a strong tailwind. According to the German glider forum, it is a Jantar. Winch launch, rope break, 180 to a downwind landing on a parallel runway. Got a tad slow and when he applied left aileron, the right wing stalled. |

Interestingly, a careful look at the slowed down version shows that (s)he pulled the spoilers out at the last minute before hitting the ground.... I would guess out of panic or something.

According to the German glider forum, it is a Jantar. Winch launch, rope break, 180 to a downwind landing on a parallel runway. Got a tad slow and when he applied left aileron, the right wing stalled. The unanswered question is why turn? If the winch cable breaks at 80m almost by definition there's room to land ahead on a normal airfield, especially with the sort of wind the sock is showing. Was this at one of those glider-only fields that I'm told some German clubs use or like I've heard Drury Hill in NZ described? The type with a small launch/landing area and the winch set up at the end of a farm track some distance away? Wish I knew what that airfield looks like. BTW, according to the Sailplane Directory a Jantar looks similar to that but has upper and lower surface brakes. I could only see top surface brakes in that clip, so my guess would be that its a DG-500 rather than a Jantar. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |

almost by definition there's room to land ahead on a normal airfield, You may not have realized that the two operative words in that sentence are "almost" and "normal". Knowing nothiing about the particular field that accident happened, I give the pilot the benefit of doubt and just believe that he had his reasons. brakes in that clip, so my guess would be that its a DG-500 rather than a Jantar. :-) When the discussion started in that forum, they talked about a DG-500. Later they corrected it to Jantar-1. Always according to that forum (I know nothing about the Jantar), in that glider you can stall a wing by applying ailerons, which perfectly explains what I see in the video. But frankly, I don't think the tipe of glider matters. |

I wrote that rather carefully. You've rather distorted what I said by skipping what I went on to say about the shape and size of the field. On my club field turning at 80m would never be necessary because the runway is mown grass 1000 m long by 100 m wide with the winch at one end and 200-400m of landing area behind the launch point. Judging from the trees etc. in the background of the clip that is almost certainly not the case where the accident happened. I give the pilot the benefit of doubt and just believe that he had his reasons. Agreed. If we knew what the field looked like maybe we could all learn from his sad experience. -- martin@ | Martin Gregorie gregorie. | Essex, UK org | |
