STS-121: More on the Foam issue

It wasn’t just a crack in the foam - a piece of the External Tank’s insulation actually fell out. Will this cause another delay? NASA reports:

launch, as engineers continue to investigate a piece of foam that came off the external fuel tank. The foam — from a bracket that holds the liquid oxygen feedline in place — was not big enough to have damaged the shuttle had it come off during flight.

The mission management team will meet again tonight to consider the issue.
