Scary story about landing on a Lake Tahoe golf course

We have a couple of water landings per decade. Nobody was ever killed or hurt, but from our statistics it can be quite expensive. One glider had leading edge of wing split open, flaps can be damaged, especially proper landing flaps. Canopy is often cracked. Wet instruments are dead instantly, or latest in few years.

Schempp policy for water landing is that all pushrods get changed in the gliders, they cannot risk corrosion and resulting ADs 10-20 years later. I once asked factory guy how much this is, answer was that around 20k euros (lots of holes in wings).

Doubt there was much left of this glider after it was washed up on the
rocks.

Cowabunga! An accident report done by someone knowledgeable of aviation
uninfected with the "headline virus." Watching this was a (pleasant) first in
my experience with "these sorts of events." Kudos to the reporter and
rescue-assisting pilot. "Well done!" all around.

Oh yeah. Sounds as if two glider pilots were Seriously Fortunate given (as i
infer) "the usual self-inflicted" circumstances. Can't help but wonder who
bore the salvage expenses...

Duo Discus Turbo. Wonder if this as another case of over-reliance on
the motor?

Hey, it's drizzling & I'm retired...and so with indoor time on my hands, and
linking from the above to the BGA report:

https://members.gliding.co.uk/wp-con...cus-G-CJUM.pdf

And if the above link doesn't directly-pull-up the BGA pdf related to the
incident, then a post from MacLaren1 on Oct. 15, 2019 "well down" the comments
listing has the link that got me there...

As earlier surmised/inferred, "Nothing new to learn here," likely applies to
the more thoughtful/curious/self-aware "glider-flying types"...yet GOBS to
absorb for those not quite-yet so jaundiced. F'r'example (and in no particular
order): avoid "getthereitis"; ALWAYS have (at least) a Plan B; could this be
*you*? [excerpted from the BGA report - "The theory states that individuals
make their decisions based on the potential value of losses and gains rather
than the final overall outcome."]

BGA report said the ship was lost at sea. When people talk about large
amounts of air trapped in the structure, there's very little actually
sealed in there, it just takes a while for the thing to sink.

Other consideration is that a lot of pilots now have LifePo4 batteries onboard. Wonder how those fair in fresh water landing and if any concern.

Salt water landings... yikes, the corrosion. Imagine it would trash the instrumentation.

As long as the cells in the battery aren't damaged enough to expose the innards to
the water, there shouldn't be any problems. I suspect damage to the battery is
much less likely in a water landing than a land landing.

If you trust Schempp, Dave Nadler Arcus M broken apart in the air 2 years ago and we still have no answer ?
