How is this for a grabber? I have a full scale pilots license,and have always been told that it is vacuum on the top of the wing that gives it lift. Now if that is so ,how does a spacecraft maneuver in outer space where there is total vacuum[no pressure]? Or are the old ideas to simple
as to how a plane flies? Or this one,if a tree falls in the woods and there is no one around to hear it,there is no noise.
