There is more to it than that. Not only does flying require up and
down, they have to be in the right place or the craft will be unstable.
This is why most conventional aircraft have a tail that pushes down,
to counteract the wings that push up. Push-ups are tiring, and after
doing push-ups I have to lie down. If a plane had to do that all the
time we'd never get anywhere, so the down and the up are both put on the
plane. The down is on the tail (when you fall down, you fall on your
tail) and the up is on the wings.
Major snip for brevity.

Well Jose you just provided additional areas of needed research and that more
money must be spent on my "research" projects:-)

I am now constructing a push up outfit with feathers on top in the proper ratio
and down on the bottom. Hmmm sounds like that's just where down should be "on
the bottom". I should be able to perform effortless push up's with it and then
go outside and go fly around a bit to cool off.
