remember when writing an essay start general but then get specific. >(generalize, but bring in, thesis/sentence of topic) -(specific) -(specific) -(specific) <(restate the thesis/sentence of topic and relate to a general audiance). your first sentence could be something like - throughout time many heroes have been chosen, but only those heroes that take action become legends. the passangers on flight 93 were among those chosen and a few of them took that action that valiantly saved our capitol. after this sentence starts general ("throughout time") but brings it into specific("flight 93 passengers"). the next sentence,thesis, would be an answer to the thesis question which might be "what makes the passengers on flight 93 heroes?". you could answer with the thesis "It was the actions of these passengers that made them heroes, not the money in their pocket or the clothes on their back." then you would make at least 3 ponts of evidence proving this thesis, and then conclude by restating the thesis and relating the essay to a general audiance. remember a narritive essay doesn't have 1st(I) or 2nd(you) person.

…I know that is what this Yahoo Answers thing was designed for…but I can’t imagine someone else writing something as big as your opening paragraph (what will set the tone for your paper) and you finishing the rest as a good thing.

Spend some time reading up on it, until you’re completely consumed in what your reading. (until you’re feeling emotion about it…i.e sad, mad, confused, curious etc.) About that time start writing your thoughts about it down, and formulate that into your first paragraph.

It seems to be an inappropriate topic as it is something so very traumatic to a great deal of people even to this day.
