Orbital Sciences Antares rocket explodes after liftoff
I had a close friend who worked on this.  Everybody in our lab stopped working this afternoon to watch it launch, and to cheer our friend on.Definitely went from "YAY!" to sad really quick.It's been said other places in this thread, but to echo it again: I really feel for all the engineers involved in this.  That's got to be devastating.To everybody: failures suck, but big spectacular failure is directly correlated to the difficulty of what you're trying to do.  If you're failing, you're doing something right.Back when I used to mountain bike a lot, it was a personal "joke" that I wasn't really riding unless I crashed at least once.  That's how I knew I was pushing myself to improve.Don't fret the failures.
