Boyd, this video shows how it works. I'd highly recommend muting the music.Can you explain that?
Al... you need to read that again:16,000 ft would almost graze some of the Rockies.I assume aerials are done at greater heigths there? In Alaska 16000 ft would not even cut it in some areas
That is very interesting! Quite a talented man. His son follows in his footsteps.Helicopters were his first love, and he missed being able to tinker around with that stuff himself. Here he is in 1952 (I think) in the XH-20 "Little Henry" (his middle name), an experimental helicopter with little ram-jet engines on the rotor.
So maybe @Teegate can tell us something about this non-existent hill?The area is really remote and to get to it we had to cross a cedar swamp and follow an old trail to the upland that the map calls Hay Landing (Hayland Hill).
Well, the mystery is that the USGS 24k topo shows a little hill there, as I posted aboveNice high piney woods but I don't remember a hill there.
