On Sunday afternoon June 19th Joseph Patton died in a glider accident
at Bergseth Field near Enumclaw, WA. Joe had been flying for a few hours in his motorglider, came in for landing with too much altitude, stalled and crashed. Joe died instantly. There will be a visitation (opportunity to pay last respects and talk with his family) on Friday June 25th from 4 to 8 PM at the Bonney-Watson Funeral Home. The funeral home is located at 1732 Broadway (between Denny and Pine, across the street from the Seattle Central Community College) in Seattle on Capitol Hill. Parking is available on the north side of the funeral home. Funeral Services will be held in the chapel at that same funeral home on Saturday June 26th at 11:00 AM. |

I am new to sport (2 years). Because seems so difficult to stall a
glider when intentionally practicing both straight ahead and turning stalls I have a hard time understanding why it is such a common reason for a tragic incident like this. Hal, A credible witness observed that by the time Joe realized he was in trouble, he was too high, had a slight tailwind and had too much energy for a normal landing. If he proceeded straight ahead he was certainly going to overrun the runway and end up rolling into the trees. For some reason he made a hard turn to the right followed by a hard turn to the left. He ended up low (about 50' AGL) and slow near midfield. Out training teaches us to keep our speed up, but at very-low altitudes our human nature tells us to pull back on the stick in a turn to stay away from the ground. I didn't understand this very well until I went up with and instructor who had me practice some slow skidding turns (like the kind of turn we might be tempted to make from base to final if we don't have much altitude). I found that stalling and spin entry can be much easier and more dramatic than I thought. I am glad you asked about this. Mark Nyberg |

It sounds like he made a reasonable choice by adding some length to his final by doing some turns. Someone mentioned the field was 2000 feet or so. Being able to loose enough energy to be slow and midfield at 50 feet sounds like he achieved his goal all too well. 1000 feet to land from 50 feet sounds tight but doable especially if you're already slow and need to speed up to do a proper flare. The thing I figured is that it would *look* tight and maybe impossible especially if the drill at that field is to land on the numbers (I don't know this). I do know I've never been drilled with "Fly over most of the runway and stop with the nose at the far end of the runway." If this was the situation he was in, I could see how it ended badly. My condolences to his family and friends Shawn |

If that didn't stop the glider in time, aiming between the trees as they approach might avoid serious injury, as likely the speed would be slow by the time of collsion. I'm not sure I would think of this if I were in that situation, as the ground would seem to be going by rapidly with the tailwind, and the trees would likely look very threatening. -- Change "netto" to "net" to email me directly Eric Greenwell Washington State USA |

It is the fences that scare the hell out of me. Post 9/11, barbed wire is probably much more prevalent on airport fences than it once was, just about neck high when you are seated in a glider.

Airnav lists the runway length at 2100'. The Terraserver image from
1998 shows it is about 2300'-2400' from the trees at one end to the trees at the other end. I've never been there, but the lengths and images suggest a field with very small margins for error. This reminds me of why I am thankful for the short field landing practice I was urged to do when I first started flying my ASW-20. My instructor told me to put traffic cones next to the runway 300-400 feet apart and practice touching down at the first cone and stopping before the second. Repeat three times every visit to the glider port the first month or so. Now a 2000 foot runway looks like Los Angeles International. - Mark Navarre 2/5 black ace LoCal, USA remove brain to reply - |

I've been thaught the two methods. In Belgium an instructor told me to make
S-turns when high on final, in France this seems to be illegal and a steep dive with full spoilers is recommended. About aiming between the trees, this makes me wonder. In a glider with a span of let's say 15 to 18 m you probably end up hitting a tree with one or two wings. An article in our club magazine about outlanding mentioned that stick full forward and intentionally ground-looping as the method of choice. The stick forward would bring the tail up and prevent it from snapping off. Speed would be down and the glider and more importantly yourself would survive. Anyway, there is no more damage than hitting a tree with a wing. Joeri. "Eric Greenwell" schreef in bericht ... Shawn Curry wrote: It got me thinking about what I would do in the same situation.

I'm not sure I would think of this if I were in that situation, as the ground would seem to be going by rapidly with the tailwind, and the trees would likely look very threatening. I once landed my DG-400 (1,000 lbs gross) on a 1,200 ft runway, stopping a little more than halfway. I wanted to clear a stand pipe on one side of the runway, so I gave up about 200 ft. This means I really used about 500 ft to stop. This was a real life situation-not a simulated one. This guy, flying a lighter glider than mine, should have been able to get down from 50 ft and be fully stopped with 1,000 ft of runway he had left. In any case, going off the end of the runway at low speed sure as hell beats going in vertical. S turning at 50 ft is highly unadvisable. Tom Seim Richland, WA |

I don't normally comment on these posts for fear of upsetting someone, but
in this instance it is clear the report is confused, one does not crash after a stall because of having too "much" altitude. Rich... Joe had been flying for a few hours in his motorglider, came in for landing with too much altitude, stalled and crashed. |
