Scary story about landing on a Lake Tahoe golf course
Ahh good points. I’ll take a look at my POH when I get my glider out again.

I've seen traces that retreat to the Carson valley via the 50 gap. I did that once, and pretty much followed the terrain down 50. Even though no useful ridge lift inside the bowl, plenty of sink on the lee side. Crossed the valley and ridge soared back to Minden. Won't do that again... Glad you're OK Ramy! |

Due to the experience gained on that occasion it is supposed, that the aircraft will not skim across the water, but that the whole cockpit area will be pressed under the surface. If the depth of the water is less than 2 m = 6.5 ft, the pilot is in the greatest danger. Touching down on water is, therefore, recommended only with landing gear lowered, and as the only way out. |

I know a guy who landed in a lake near Arlington, WA. Two fishermen in a nearby boat came to give him a lift to shore. He insisted that he had landed in shallow water, and jumped up and down in the cockpit to prove it - the glider was absolutely rock solid. They said no, the water was 10 ft deep. He didn't believe them and jumped into the water to prove it - he promptly sank in over his head. The glider was towed to shore and damage was limited to one mechanical vario. Tom |

I've seen traces that retreat to the Carson valley via the 50 gap. I gather the golf course in Kings beach has also been landed on, but these seem very chancy. Anyone else have a half decent plan B for the Tahoe basin? John Cochrane Sergio (and a few like him) would enter Spooner Pass with sufficient altitude to take one pass at the Elevator, then exit if it did not work. Even in the best circumstance, this is a very risky move. Most of us Truckee regulars believe that if you are low enough to feel any ridge lift there, you are WAY TOO LOW. A retrieve from Carson is very inexpensive compared to even slight damage to a glider, let alone a funeral (and attempts at the Elevator have resulted in both). Ramy found an empty fairway, but even checking it with a crosswind pass does not guarantee that some duffer won't wander back out on your final, having retrieved his slice from the woods. |

That failure only made obvious the chain of errors the pilot made prior to its attempted use. |

Scary story about landing on a Lake Tahoe golf course
Interesting, I had nearly the same experience. With the wings providing stability it did seem rock stable, and thought I might be sitting on the bottom. But as I entered, I too was over my head in the water.

Starting an electric motor now counts as a "save"? :-) I'm not counting, but sure, if something "saves" you from an undesired landing, let's call it a "save". If the method of your save is important to anyone, they can always ask you for details. It doesn't save your scoring in contests, of course, unlike blundering into lift on the turn to base (for example). -- Eric Greenwell - Washington State, USA (change ".netto" to ".us" to email me) - "A Guide to Self-Launching Sailplane Operation" https://sites.google.com/site/motorg...ad-the-guide-1 |
