Emergency responders in the lobby of the north WTC tower hear an unconfirmed report of a third plane heading toward New York. Consequently, Assistant Fire Chief Joseph Callan orders all firefighters to evacuate the tower. The third plane report is soon found to be incorrect. One firefighter tells a colleague over radio, “That plane is ours, I repeat, it is ours.” Rescue operations therefore continue. [New York Times, 7/7/2002; New York City Fire Department, 8/19/2002, pp. 32; Fire Engineering, 9/2002; Associated Press, 11/16/2002] The source of the incorrect report is apparently Richard Rotanz, the deputy director of the New York Office of Emergency Management (OEM), who is reportedly in the OEM command center on the 23rd floor of WTC Building 7. A Secret Service agent in WTC 7 reportedly told him there were unconfirmed reports of other planes in the air. When OEM Director Richard Sheirer called Rotanz some time after the second WTC tower was hit, Rotanz relayed this information, telling him there were “still planes unaccounted for that may [be] heading for New York.” Sheirer then told people in the North Tower lobby “that another plane was on the way.” Journalists Wayne Barrett and Dan Collins, in their book Grand Illusion, blame Sheirer for “instantly converting unspecific information into a very specific false alarm.” This false alarm quickly ends up on fire and police department dispatches. Sheirer is apparently so unnerved by it that he instructs the police department aviation unit to not let another plane hit the WTC. As he will later tell the 9/11 Commission, though, “We were grasping at straws,” since no police helicopter could “stop a commercial jet going over 400 miles per hour.” [Firehouse Magazine, 9/2/2002; 9/11 Commission, 5/18/2004 ; Barrett and Collins, 2006, pp. 32-33] Emergency medical technician Richard Zarrillo is currently in WTC 7, and is informed by an OEM rep there of the alleged third plane inbound for New York. While the rest of Building 7 was evacuated earlier on (see (9:03 a.m.) September 11, 2001), this false threat reportedly leads to the evacuation of the OEM command center as well (see (9:30 a.m.) September 11, 2001). [City of New York, 10/25/2001] (However, some accounts indicate the command center may have been evacuated earlier (see (Soon After 8:46 a.m.-9:35 a.m.) September 11, 2001 and (Shortly Before 9:03 a.m.) September 11, 2001).) Soon after hearing this false report of a third inbound plane, Mayor Rudolph Giuliani, Police Commissioner Bernard Kerik, and OEM Director Richard Sheirer will all leave the North Tower lobby and relocate to a temporary command post on Barclay Street (see (9:50 a.m.-10:10 a.m.) September 11, 2001).
