 Susan Kilrain, who we just heard from there, was pretty clear that these things are mapped out when it comes to launch dates, for example, even though they knew that there was this helium leak on board, and said that despite any pressure to go ahead with the launch, if it wasn't safe, they wouldn't have done so. I mean, hindsight is a wonderful thing. Does it now look like it was a bit of an error to launch and not wait a little bit more?
