SUMMARY: NASA controllers grounded the shuttle fleet for at least two more months on Friday after they discovered small fuel line cracks - so far they've uncovered 11 in the four shuttles. All the cracks are very small, only a few millimetres in length, but NASA is worried that a piece of metal could chip off the fuel line and fall into a main engine during liftoff. This could have disastrous results. Two shuttle flights are currently on hold until the problem can be fixed.

It makes me wonder, what sort of metal are they using? Shouldn't they be using a high stress polymer?

That would be what happens when you contract the work to the lowest bidder

There really is too much waste. In the 70's my hubby worked for a Fed. contractor boxing the rubber eye rings for night glasses. They came from the factory 24 in a plastic bag, and they were in a large box. Cost: $0.02 each. He took them out of the containers and put each in it's own plastic bag, 2 to a box, 12 little boxes to a larger box, and then that went into a shipping container. Cost: $ 12.50 per plastic bag.
