Safety officials have said that Discovery
is not safe to fly, and that modifications carried out to prevent chunks of protective foam breaking off where not enough.
Conflicting views on the modifications haven’t helped matters, and Nasa administrator Michael Griffin told a news conference “I can’t possibly accept every recommendation given to me by every member of my staff, especially when they all don’t agree.”
Fair enough I guess, but if I was about to blast seven people into space on a multi million dollar firecracker, I would want to make sure everybody was all agreeing! Any doubts by anybody and I would want to know why and double check, possibly even triple check!
