Old news but i'd like to discuss, I mean for a stationary shuttle not even undergone launch and the stresses of gravity and other stresses.
A window panel falls off whilst sitting there like a duck? It's kind of worrying imagine if nothing happened until after launch :/
Lets hope nothing goes wrong, it's about time we get back on track for space colonisation!

It's nice to see the director or whoever it is coming out flat saying, "probability something bad happens?...oh 25%". But they know the risks, it's well worth it, they are our pioneers and god knows what stuff we'd have in the future ;o
