LAST WORDS: Challenger Astronauts last words caught on tape

This is the real thing, a home movie found years after the Challenger disaster. It documents the reactions of some ordinary people standing around trying to figure out what is going on. In short, they're like everybody else. Even NASA didn't know what to say, except for that "malfunction" remark about five minutes in. People think this video is humorous, and in a way it is, but nothing else about that day was. Nor is the fact that the astronauts all survived the explosion and were alive for the 2 1/2 minutes it took for the capsule to hit the water. That's a very long time to be doomed. 

So what is the "last words" in the title all about? Just got mixed up, I guess. I get that way sometimes. Mixed up.
