The energy difference between a rocket engine and an airplane combustion engine is huge. Rockets are all about raw energy output and are essentially a bomb. The fuel is volatile, and rockets use a lot more fuel than planes. If a failure happens with rockets, the whole thing usually ends up blowing up catastrophically. Rockets are inherently more dangerous. But hey, more power to them. I would love it if we can make rocket flight safe enough for everyday use by everyone.
