** Definately not for the faint-hearted --- **
We called it a "high overhead" approach, Pickett.
I have described it as swinging a yo-yo around in a circle on its string, the ship just pivoting on its rotorhead. I knew when BonBon had it really hooked up because (he always went left) I could sit in the left door with my elbows on my knees, look straight "down" past my toes, and see the opposite horizon and some sky, upside down
BonBon used it maybe a dozen times while I was with him, when we weren't sure if ANY side of an lz was safe for a normal approach, or if there was arty on the approach side, something like that.
Then he used it one time when we had a pain-in-the-ass O-5 on board. He had that sumbitch crawling around on the deck like a poodle scratching for traction on ice, sure he was gonna fall out. The boy got out on the pad and barfed his innards out; it was great. Truth is, the G-forces wouldn't let you out if you wanted to get out.
Some of this stuff was real fun...
