Interesting! But don't use this to run a nuclear reactor. Or airplane. ** :-) Aircraft designs can tolerate a limited amount of deviation around their center of mass. Beyond that, the control surfaces of the aircraft may not provide sufficient force to maintain positive control. A common problem is too much weight in the back of the plane, which prevents the pilot from pitching the nose down. Worst is on takeoff, but any time the plane gets too slow, it will stall. And loose lift. On takeoff or landing like this, often the plane will flop over very quickly. My rudimentary pilot training included lots of practice keeping the plane balanced properly during maneuvers. A Cessna 172 is a very robust and forgiving design, you have to really try to get in trouble like that. But it's vitally important to maintain positive control. Especially on approach to landing, your mind is paying attention to many things. At one air park where I was flying, there was the crumpled remains of a perfectly nice airplane, upside down to one side on the grass. A pilot was undergoing periodic proficiency training, and the examiner pulled power on approach to simulate an engine outage. And boom they were upside down with no time to recover before hitting the ground. Even experienced pilots fall. (They survived. Serious injury.) ** (Sun/Oracle license for Java -- not JavaScript at all, but an example I'm familiar with -- specifically prohibits usage for air traffic control or nuclear power. Probably these days, that would include autonomous vehicles as well.)
