But for more than two years, no shuttle has flown.

I don't think it makes a lot of difference for the small companies if the shuttle is flying.

It was more than two and a half years before another shuttle flew.

The shuttle will not fly again until at least February 1988.

But it's one of the last military missions the shuttle will fly.

The shuttle will be flying for a long time because nothing else can do its job.

"When the shuttle flies again, it will be safer than at any time in the life of the program."

"Obviously, this problem needs to be addressed before the shuttle can fly again."

Five hundred million dollars wasted each time the shuttle flies!

Last year, the shuttles flew eight times, one shy of the record set in 1985.
