Sootikin,
I'm not trying to be a troll. I'm ok with gliders, because they convert altitude to speed, which is turned into lift. And then friendly drafts help out too. And gliders cheat, they get the tow plane to use it's fuel.
All my life I'm taught that whenever you get an action there's a reaction, i.e. nothing's free. So I don't see how adding thrust one way gives you more than twice the thrust another way. Someone mentioned time, however there's no time in force.
Mad Flt Scientist, I invoke thee!
