Wow...yeah.

I'm slow and couldn't figure out the reference for these names. So I clicked a reference and found they are the names of the (now) astronauts aboard the shuttle. I should have guessed but I thought it might be a movie reference. I still don't understand why, "I answer for". Could you answer that?

In Space Cadet by Robert Heinlein, it's a tradition of the Space Patrol that at the end of each roll call they call the names of four men who gave their lives in the formative days of the Space Patrol. As each name is called, a cadet calls out "I answer for him" or something similar.

The names I listed are the names of the astronauts who were on the last flights of the Challenger and the Columbia.

Thanks anonymous. I'll let Carol know that somebody helped me. And you did. I definitely needed a clue, I thought these were the names of the astronauts who just went up.
