from richard zarillo's oral history:
"Maybe five, ten minutes, not even ten minutes
later, a rep from OEM came into the main room and said
we need to evacuate the building; there's a third plane
inbound. That was the only thing I really heard
because I said, Abdo, we've got to go, and we made it
down to the lobby of the building, street level, met up
with Chief Peruggia in the lobby of the building. He
said that there was no third plane but we needed to
re-establish OEM right there so we can coordinate what
was going on."
from the peruggia oral history interview:
I questioned as to what the nature of the
evacuation was. I was told that it was not because of
what was occurring across the street. No one feared
that the building was in any danger as a result of two
airplane attacks and subsequent fires, but that there
were reports of a third plane that had been hijacked.
It was unidentified, the location, and they thought it
may be coming in for an additional strike. Therefore,
they were evacuating the building."
and dont forget about the "games" on 911!!
Agency planned exercise on Sept. 11 built around a plane crashing into a building
"In a promotion for speaker John Fulton, a CIA officer assigned as chief of NRO's strategic gaming division, the announcement says, "On the morning of September 11th 2001, Mr. Fulton and his team ... were running a pre-planned simulation to explore the emergency response issues that would be created if a plane were to strike a building. Little did they know that the scenario would come true in a dramatic way that day."
and also dont forget about the "inputs" on the screens (military but maybe faa as well).
so who knows, it may not have been 93 but something got the attention of the OEM. the secret service and cia was in wtc 7. the secret service has access to flight data and from the article,"The National Reconnaissance Office operates many of the nation's spy satellites. It draws its personnel from the military and the CIA. maybe that 3rd plane was an input headed to new york. maybe thats why in the interview zarillo said there was "no 3rd plane" anymore because they called of the war games?
