Sorry, you are wrong. You are presuming that the wings are the only
source of lift on an aircraft.

Wings are the only things under discussion in such theoretical
scenarios.

No. Whether planes can fly a knife edge is. And, you didn't understand how
this is done.

As the original poster said, there
were airshow acts that use the side of the fuselage coupled with a
LOT of power to maintain knifedge level flight.

I'm sure you could use helium balloons, too, but that isn't an
automatic assumption because it is not universally true.

It isn't even a suggestion.

Did you lose every argument as a child? Is that why you live in a fantasy
world where computer simulation defines your reality?
