***I think a certain fighter pilot made that choice on 9/11. I may offend a few people so I do appologize, but I don't believe that it was a handfull of brave men that crashed the plane into the ground out in that filed (somewhere near philidelphia).***

I haven't heard if that was true. I know someone who lives there and they said that they thought the plane was brought down, but the plane came straight down, which is not how a plane would come down by a missile. It would fragment to pieces over a few kilometers or so.

In any case, the point here is a different issue since we can believe that the hijackers had evil intent. Bringing them down at the cost of the lives on board, as tragic as that situation is, must be weighed on the people and maybe even country it would save. The situation you presented is to first believe the assailant, something which you cannot do. There is nothing about the assailant which garners trust. Hence, if you cannot trust the assailant, you must suppose that your only action is to act with honor and with valor. It might seem like a cop-out to a remote moral dilemma, but stories of valor have played themselves out all too often.
