In my opinion, stunts like this are a disservice to the entire glider
community. I have a lot of respect for Klaus Ohlmann, but this makes me

Not CGI.
A filmteam consisting of some 40 people performed approximately 30 launches
in order to get the film material needed for 90 seconds of video.

The aircraft in question is a 23E, and Mr. Ohlmann would extend the motor
and perform a 180° turn, landing uphill under reduced motor power,
allowing for a quick turnaround for the next shoot.

Now for getting out of the hangar without damaging anything as the wings
pass through the beams.. ..that is some really advanced thechnology that i
am not yet at liberty to discuss in public
