As a kid I had dreams about flying where I could run and jump and feel the lift in my arm pits holding me up. Later on I discovered this is the way some of the early hang gliders were working. About the time I discovered hang gliders I realized I had severe issues with height. So much for flying with the birds that way.

The height problem is not there in any form when in an airplane of any kind that has a full fuselage around the bottom. Maybe it is my butt that has the height problem! Strange.
