"I remember the day that the Challenger died.
I remember the blast; I remembered I cried.
I remember the day when that proud ship fell,
and the seven who rode on that pillar of hell.
"Those harsh little men with their mean little minds.
With their schedules and costs and bloody bottom lines.
Who contract and kickback, who buy and who sell
and who never will ride on that pillar of hell.
"... the seven who rode on that pillar of hell."
I would put "contemplative" as the mood, but that has a smiley face on it.
