Here's a random question about Die Hard 2, which I've seen several times.

Why didn't those planes circling the airport for an hour or two just decide to land at another airport? There are many other airports they could have reached even in the blizzard.

And if it was so easy to get them to land just by Bruce Willis lighting a trail of fuel with a cigarette lighter, why wasn't this done earlier on? Or bring in lights with a generator?
