All day something rubbed me the wrong way, and I'm not sure if I'm right on this or not. But is "debris" the right word for spotting something falling off the shuttle or fuel tank or whatever? I looked it up in dictionary.com and Merriam-Webster and neither gave a definition of "debris" that seemed to fit the context. At best it's a piece of something that's been destroyed, not something that has one piece fall off. Thoughts?
