[P-40]

Would you or would you not kill your mother if she was suffering?

In certain circumstances, yes I would.

Now your answer about flight 93.

[Grizzled Bear]

Assuming I have the authority to make this decision...

You specifically referred to flight 93.

Once it was clear that the planes were used as missiles I would give orders to attempt to force a landing. Flight 93 spent long periods of time over sparsely populated areas so there would likely be less collateral damage.

I would order it shot down as a last resort.
