Paul:
The Hiller flying platform better known as the "flying man hole cover"
is now on display at the Hiller Museum, San Carlos, Ca.

Incidentally ANY failure of this machine and you are on a lead brick.

The one man air droppable helicopter for rescue of downed pilots did
work pretty well.  25 were built and 3 are on display at the Hiller.

I have got to get up there one of these days.
