The lift to thrust ratio and other features of the take-off/landing and
short flight dynamics of some insects (e.g. butterflies) break the rules
of
flight/energy use etc as they're understood by current engineers and
physicts.... the insects shouldn't be able to do it they way they do,
but
they obviously do ;)
