There is no fundamental limit to the pressure that can be generated under the wing. With sufficient thrust and proper angle of attack, a brick can produce sufficient pressure underneath it to generate lift.
minus-squareleftzero@lemmynsfw.comlinkfedilinkarrow-up1·12 hours agoFair enough, yet unless I’m mistaken most planes don’t rely on people throwing bricks at them (which would be quite risky anyway, for unless they throw them faster than escape velocity they’re bound to come back down eventually).
