After the Iron Curtain fell in the 1980s, I invited one of my hang gliding penpal friends from Czechoslavokia to spend the summer with me in the USA.
Without access to aluminum tubing, I was amazed to discover that these incredible free-flight enthusiasts had used lengths of steel pipe and spent weeks drilling hundreds or maybe thousands of little holes to lighten each section.
The sails were plastic and these heavy homebuilt gliders would actually get off the ground and fly if one could run fast enough.
So for the next Dockweiler Ironman, I've asked Frantisek to bring one of these old gliders over for BobK to make 100+ launches with!
This will be the first true "Dockweiler Ironman."
I'm sure BobK is up to it.
I sure as hell am not.
