The Flying Cart is a true ground-effect machine
(GEM). It has no wheels. It glides on a cushion
of compressed air supplied by a modified chainsaw engine and a four-bladed wooden prop.
I built the “airframe” of ordinary lumberyard

as a search for an improved wheelbarrow—it
happened the other way around. The building
itch came with the first story I read about air
sleds, and intensified with each story thereafter.
It was a challenge to build a totally new kind of
vehicle before all the development problems were
trampled to death—and all the unanswered questions were answered—by multimillion-dollar research programs.
I doodled the requirements. It would have to be:
• Reasonably easy to build with ordinary
• Adaptable to continuing changes and experi
