NASA is taking this business of stuff falling off the shuttle and fuel tank pretty darn serious. But what suprises me is that tiles have come off before. If I remember correctly they have some fudge room if they loose a couple of tiles. But the external fuel tank is another story they are not at all happy about that. So hopefully they can get this figured out and keep on moving down the road.
Thus far though over 200 people are pouring over all of the film and data that was collected to see if they can figure out what fell off. [SpaceToday]
