I joined the early on yesterday, Jimson. For some reason it didn't launch. At 15 past the hour, I was the only on in mission and it still hadn't launched, so I moved on. May have been operator error on my part. Keep up the great work! ![salute :salute](http://bbs.hitechcreations.com/smf/Smileys/default/salute.gif)
Hmmm, not sure why that would be.
I know that if you join and then take another flight before launch, the mission will drop you, but otherwise I don't know.
