The Reuters reporter who wrote this story just had to have heard this wrong. Quoting space shuttle mission specialist Charles Camarda, he wrote:
Tragically, two years ago, we came to realize we had let
our God down. We became lost in our hubris and learned once
more the terrible price that must be paid for our failures. In that accident, we
not only lost seven colleagues, we lost seven friends.
Somehow I just have to think that he said “we had let our GUARD down.”
