A manned replica was flown in England back in the Nineties, though I
suppose this is the first time it's been done from the actual Schloss
with an actual bathtub-a-pult...

Indeed, and test flown by Derek Piggott IIRC.

Find "Colditz Castle" with Google Earth, zoom out to see across the
river and it becomes obvious why this version was flown as a UAV. The
water meadow across the river was intended landing place of the
original glider, but is now wall to wall houses, roads and trees, so
these days any more or less straight ahead flight is just a straight
glide to a crash site.

You can see from the pictures that the replica had no airbrakes and so
little ability to make a precision landing. I think the idea must have
been to prove that the launch would work and, if it did, the intention
was to crash the glider on the far side of the river to show it could
fly that far and to hope it could be done without hitting anything or
anybody.

There is a possible, though rough looking, landing area on the far
river bank to the right, but that would require a 70-80 degree turn,
which you may not want to do on the first launch of a new aircraft over
a built-up area, regardless of whether it was manned or unmanned

Thanks, Tony.

Thats a better story than the one I saw, and with much better pictures:
the only one I've seen before is the second one. The first is
particularly interesting, as you can tell from the view of the castle
that they did turn right and put it on the bit of the riverbank I
described as 'rough-looking'. Its obviously much shorter grass and
smoother than I'd guessed from the Google Earth view.

I notice that their airframe was half the weight of the original, so I
have to wonder if the wing would have come off forward through the
pilot's head if the structure had as much material in it as the original
- and if it would have launched so easily.
