The Crane was the last of Igor's personal babies. It was the direct outcome of the S-60 experiments that were done with the piston H-37 drive train.
Here is Igor and his engineering team out for a quick flight underneath the first crane.
Never mind computer designed, here you have a real case of putting your faith on the line!:
On that S-60 flight, the pilot was Jack Peterson, and his co-pilot was Jim Kay.
After takeoff, Jim checked to see if the platform was behaving itself, as he glanced back to look, he said to Pete,
"Pete, don't do anything sudden!"
"What's wrong, is the load swinging?", Pete asked.
"Nope, worse. The Old Man is up and walking around!"
Igor had undone his belt and began strolling around the tiny platform, oblivious to the fact that there was no railing, or that they were 1500 feet above the ground! After much strenuous gesturing, Igor got the hint and sat back down!
