After the bombing, Hill (who spoke Arabic and was a convert to Islam) visited many mosques in the New York area and across the Hudson in New Jersey. At the Turkish mosque in Patterson, everyone was friendly and pro-American and hoped the bombers weren't Muslims. From Heart of a Soldier by James B. Stewart (Simon and Schuster, 2002) (Google Books link):
But at every other mosque, Hill was struck by the intense anti-American hostility he encountered. Though these were not his own views, he barely had to mention that he thought American policy toward Israel and the Middle East was misguided, or that Jews wielded too much political power, to unleash a torrent of anti-American, anti-Semitic rhetoric. Many applauded the bombing of the WTC, lamenting that it hadn't done more damage. “Those are the towers of Jews”, he was told at several stops. Then his hosts quoted from the Koran [Sura 4:78]: “Wherever you are, death will overtake you, though you are in lofty towers in the sky.”
On 9/11/2001, Rescorla and his two lieutenants, Jorge Velasquez and Godwin Forde, were last seen in the South Tower on the 10th floor, heading upward, shortly before it collapsed at 9:59 A.M.
