Couldn't do this now--in my very young years, maybe! My nephew did this--among all the interesting things he has done. His latest is with a team that is going to find Amelia Earhart's plane--yes, that's true. Also he has the world record for the highest balloon flight and skydive. In fact, his space suit just got put in the Smithsonian. We all wonder what his adventure will be when this latest is over!
