At 8:50, the Aviation Unit of the NYPD dispatched two helicopters to the
WTC to report on conditions and assess the feasibility of a rooftop landing or
of special rescue operations. [...] At 8:56, an NYPD ESU team asked to be picked up at the Wall Street heliport to initiate rooftop rescues. At 8:58, however, after assessing the North Tower roof, a helicopter pilot advised the ESU team that they could not land on the roof, because "it is too engulfed in flames and heavy smoke condition."
By 9:00, a third NYPD helicopter was responding to the WTC complex.
NYPD helicopters and ESU officers remained on the scene throughout the
morning, prepared to commence rescue operations on the roof if conditions
improved. Both FDNY and NYPD protocols called for FDNY personnel to
be placed in NYPD helicopters in the event of an attempted rooftop rescue at
a high-rise fire.
[...] Others ascended to attempt to reach the roof but were thwarted by locked
doors. At approximately 9:30 a "lock release" order—which would unlock all
areas in the complex controlled by the buildings’ computerized security system, including doors leading to the roofs — was transmitted to the Security
Command Center located on the 22nd floor of the North Tower. Damage to
the software controlling the system,resulting from the impact of the plane, prevented this order from being executed.
[...] At 9:06, the NYPD Chief of Department instructed that no units were to
land on the roof of either tower. At about 9:30, one of the helicopters present
advised that a rooftop evacuation still would not be possible. One NYPD helicopter pilot believed one portion of the North Tower roof to be free enough
of smoke that a hoist could be lowered in order to rescue people, but there was
no one on the roof. This pilot’s helicopter never attempted to hover directly
over the tower. Another helicopter did attempt to do so, and its pilot stated
that the severity of the heat from the jet fuel–laden fire in the North Tower
would have made it impossible to hover low enough for a rescue, because the
high temperature would have destabilized the helicopter.
