What does "H" stand for (As in "About 0.87 H" next to the WTC 1 impact point.) Could someone who knows either add a legend or just spell it out in the two places it's used? Alex 19:14, 10 June 2007 (UTC)

I assume it means height (of the towers), but it's not at all clear. It would be helpful if someone who knows how to modify these things could do so. Vilĉjo 10:43, 10 October 2007 (UTC)
