I can just imagine you sitting there with a little astronaut helmet on, eating astronaut ice cream, and drinking Tang while watching the Challenger go up. Just slowly taking off your helmet, pouring out your tang, and chunking the astronaut ice cream in the dumpster. Then little InternetUser2012 just kind of saying to themself, "Yeah I don't know what I was thinking. That shit is WAY more dangerous than I thought!"
In fairness, just reading about the Challenger also made me do about the same thing when I was a kid. I thought going to space was about the coolest thing I could think of to do. Then when I was in the like the 3rd or 4th grade I read about the Challenger and was like, "On second thought, I don't think I want to go to space after all."
