乐生活It was crazy when Apollo landed on the moon. I just saw that there was an idea of a super helicopter that could carry Saturn V’s huge first-stage rocket and even imagine catching the first-stage rocket in the parachute overhead (this is to recover and reuse?). A helicopter’s rotor alone is longer than a football field. The idea has not been funded for research, but is only at the conceptual stage. But it’s crazy enough… Source: The Space Review
