Wow. I was in freshman geography class, and it was surreal for a number of reasons.
I attended a parochial boys-only prep school that year, and the quality of teaching was...shall we say...uneven. Our geography teacher in particular claimed to be a professional wrestler (if anything he was a luchador) and was a notorious bullshitter in general, so when we entered his classroom and heard that the Challenger exploded, the common response was 'yeah, right'. Then we went into the a/v room and watched the replays for about 15 minutes.
