One woman died after being hit by a piece of flying debris in Toronto.

One more piece of debris from what had once been a man's life.

About 40,000 recovered pieces of debris have never been identified.

But a piece of debris may have broken up two or three times before it reached the ground.

There was no confirmation if pieces of debris had reached the Earth's surface.

And there's a hot source in another piece of debris.

And it tells me we found a piece of debris.

And I let the team continue to evolve so that they work to get the correct data from the particular piece of debris.

"I thought it was just an interesting piece of debris."

A piece of debris from an unknown race car changed all that.
