Few people -- present company excluded -- can claim the expertise of Buzz and Bill and Charlie when it comes to space exploration. I have to say that few people are as singularly unimpressed by Air Force One as those three. Sure, it's comfortable, but it can't even reach low Earth orbit. And that obviously is in striking contrast to the Falcon 9 rocket we just saw on the launch pad, which will be tested for the very first time in the coming weeks.
