Awesome. Thanks for proving my point for me: if something is 7 times as big and has 7 times the thrust, that would make it proportional to the smaller plane. 7 times 1/7 equals 1. So it's a one to one ratio. What uni gave you that bachelor's again? I'm bringing a class action suit against them. I've read Newton's stuff on gravity, Einstein's general theory of relativity overturned his theory, but please don't try to absorb that, who know what could happen. Plus, gravity doesn't exist, so those fools were wasting their lives, right? School's back in session, go take a potty break...
