FAA New York to Command Center, Virginia
September 11, 2001

MANAGER, NEW YORK CENTER: We have several situations going on here. It's escalating big, big time. We need to get the military involved with us . . . . We're, we're involved with something else, we have other aircraft that may have a similar situation going on here. . . .

The "other aircraft" New York Center referred to was United 175. Evidence indicates that this conversation was the only notice received prior to the second crash by either FAA headquarters or the Herndon Command Center that there was a second hijack.
