>>18912879Planes stay in the air due to the forces of lift overcoming weight, speed increases the effectiveness of lift forces, so as long as you make a very light and strong craft, you can go very high and very fast.
Kelly Johnson((RIPBUH) knew this which is why he created a plane out of titanium that could fly 100,000 feet high at mach 4+.
