LOL. I never heard of that and I haven't flown with anyone else yet.
Thanks for the "heads up", in case I ever get into that situation.

That is a good reason to "personalize it" so you can tell the difference. Where I fly indoors we will regularly have 5-6 champs or vapors or embers up at once and regularly have planes fly into the wall unattended. When a high performance glider becomes the "must have" plane (Supra currently) it is very easy to see 3-5 of them coring the same thermal in a launch group and suddenly notice one wander out. it usually isn't immediate since you are all giving about the same inputs to circle the same space but at altitude is hard to see small trim details and even different colored large stripes on the bottom blend to gray/black. it's worse when the one you are watching wanders out because the pilot needs to come down to make his time and now you need to discover which remaining ones is yours... I always try to put a chrome strip on my leading edges so I get a flash once per revolution from the sun. That helps at distance too as I know what orientation I must be in to see it even when specked out and I can level out and fly back by timing it. (another example of knowing your plane)

Even world class guys can do this. Still, its funny to watch that few moments of panic and confusion when you aren't on the stick
yep, and if you aren't actively centering the plane, the edge of the thermal can boot you out (under just one wing). The easiest way to tell which is yours is to reverse the circle and see which one does it. If you do it right you can do a 360 into a figure 8 and get your thermal back. It's not as dramatic as hearing a plane got into the trees behind you and having an extra pilot still flying

Why was the throttle on full when it hit the ground?

Not meaning this as a criticism because I realize that "spec-out" is following common usage in glider-speak but am wondering how it came to be that way. "Spec" is a term often used as a short for specification. When a plane gets far away it becomes a speck. Just curious.

That is an example of one of the things that makes English challenging to learn as a second language. There are words that sound the same, but are spelled differently and have different meanings. Another example is "wood" and "would". I suppose if you really wanted to be specific, it could be argued that spec'd out was being used correctly. In that case it would not be the plane that was being pushed beyond specifications, but the eyes of the pilot instead.

I had a Graupner Elektro Rookie and a Radian, both with 808 cams and CAM ALES cutoffs, fly/soar away to never-neverland.
I know the feeling. I lost my Radian Sunday. She disappeared into a cloud that was far, far away. She is somewhere in the Land of Oz. I almost cried. It felt like I lost a child. It was a real bummer.

Rate of climb is measured in FPM, not distance.

There are many types of rates in aeronautics. One is rate of climb over distance. It's most commonly used at airfields located in a box canyon.

A high rate of climb/distance is useful if you want to keep your glider close to the field, or a thermal, etc. It's not the most effective way to get the most altitude from a timed launch. Then you want to maximize rate of climb over time.

I would think that would have to factor in wind speed? For example, it the wind were a steady 20 knots, and you flew directly into it at a 20 knot climb speed, the plane would be going straight up ( in a relatively level attitude of course) like an elevator. Is that how it works?

No. As cuff said, rate of climb is measured in feet per minute. You are confusing rate of climb with angle of climb.

Not correct. Taking off into wind, for example, the best climb rate does not change but the climb angle, and therefore the ability to clear ground obstacles, is increased.
