automated, such that with minimal training, a couple months of train welcome a crew can get onboard and fly in space. and making it open to the general public, because of course you feed to be very wealthy to afford to do this, but what we're seeing with the reusability of this spacecraft, hopefully this price will be coming down. this is a great milestone and i'm happy for everyone involved. >> there was one billionaire onboard and three others who, you know, don't have a typical resume of what you would think of going up into space, right? a physician's assistant, a community college teacher. you know, this crew is -- was civilian. it was a civilian crew. they spent about six months training. how does that compare to what nasa puts astronauts through, mike? >> well, what -- as far as the training that they got for working the spacex vehicle, it's very similar to what my friend are going through when they fly on spacex. it's not that much different. maybe a little more of the automated system, in this case, for these folks. but it's very similar.
