did they realize for certain that this was not the case and that a real incident had occurred?

ANOTHER AIR FORCE MEETING CONTINUED DESPITE THE ATTACKS ON THE WORLD TRADE CENTER

It is worth noting that the failure to immediately adjourn John Jumper's meeting in response to the attacks on the World Trade Center was apparently not an isolated incident. Another meeting held by the Air Force that was taking place in the Pentagon when the attacks began appears to have only ended some time after 9:30 a.m.

Few details of this meeting have been reported, but it has been described as a "closed-door personnel meeting convened by the Air Force to discuss the rating of Air Force officers" and as "a U.S. Air Force-convened session for general officers who ratedAir Force officers." Because he was attending this meeting, Army Brigadier General Montague Winfield was absent from his position as deputy director for operations (DDO) in the National Military Command Center (NMCC) at the Pentagon when the terrorist attacks were taking place.

The meeting appears to have only adjourned some time after 9:30 a.m., since Colonel Susan Kuehl, who supervised the operations of the NMCC, and Captain Charles Leidig, who took Winfield's place as DDO in the NMCC during the attacks, have both recalled that Winfield only arrived in the NMCC after leaving it after 9:37 a.m., when the Pentagon attack took place.

OFFICERS WERE IN A 'DO NOT DISTURB' MEETING

It is unclear why the meeting went on until this time, considering it had been obvious since 9:03 a.m.
