For that reason, we have a tremendous amount of performance margin.
That's certainly not the case for some future missions that Atlas will
be flying. So we'r

Diane. I concur in you're comments particularly that failure is not alone an
indicator of incompetence. (my words but hopefully it is fair to you're
thought)

Yeap there were two oppurtunities. 45 pounds of
Ed. yeap a lot of ifs. The good news is that Peter confirms that there (was
