Water and air are both fluids, but with densities of different magnitudes.
I'd think that you'd want to develop your idea to work in water before you
tried the thinner and vastly more difficult fluid of air.

If air were more dense or gravity was less...
BTW I remember something similar in a Heinlein book, maybe "The Moon Is A
Harsh Mistress".

I knew I'd come across it somewhere!

Heinlein's most detailed discussion of man-powered flight is in "Podkayne of
Mars". The Icarus variety -- i.e. strap on wings that you flap.

There's an interesting aside in "Killer Station" by Martin Caiden, regarding
the manouvering difficulties of flapping flight in a virtually zero-g
environment. Also, in Clarke's "Rendevous with Rama" regarding a man-powered
propeller-driven craft, being operated inside Rama.
