it is likely that many inside the WTC7 building knew of the plan to demo it, and didn't come to work that day, or left before they were instructed to, just to be sure
This is an amazing statement.

How long do you think it takes to evacuate a 40 something story building.
to evacuate from the top floor it would take as long as it would take to descend the staircase. The height of the building was 186 meters, distance of a 45 degree staircase from the top would be 186 x 1.41=0.263 km walking speed is 5km per hour. 5/0.263=19.01 60 minutes/19.01 = 3.15 minutes. how long do you think it would take to evacuate the building? You believe how long it takes to evacuate a building is dependent only on how long it takes to walk down?

In 1993, when the World Trade Center was attacked with a car bomb, Pauls learned that it took more than five hours for some people to get down the emergency stairs. This was nearly three times as long as the fire protection rating for the steel.
The stairwells were smoky and the lighting had failed. Those problems had been fixed prior to 9/11, but to Pauls, the real cause of congestion was the width of the stairs.

WILLIAM CONNOLLY: Building codes traditionally have not been designed to accommodate a full evacuation of a building. Most people think that when you're in a building and the fire alarm goes off, you all go out. We all have that experience from elementary school. We've all been through fire drills, and we understand the fire alarm goes off and everybody leaves the building.
In a building that's 80 stories tall, where it's going to take two or three hours for everybody to leave the building, we don't take the same approach. The conventional wisdom, at the present time, has been that people will be defended in place. They'll be encouraged to stay where they are. People, obviously, from the fire floor will move, maybe the floor just above and just below, but other people will remain in place.

are you thinking for yourself here, or are you just clipping pieces from anti-truth websites because you have an argumentative contrary mindset.

TWO PLANES HAVE JUST SLAMMED INTO TWO NEIGHBOURING BUILDINGS This is before the second plane hit the building and before most people had any clue another was coming.
A half an hour is a reasonble estimate.
There is plenty of documentation of people who were at the eoc after the second plane hit.
It would make no sense that the command center would have been empty and turned off before the second plane hit. Mr Jennings is mistaken about his times. Didn't Mr Hess

it takes time because of congestion. You cannot evacuate a building in as long as it takes someone to walk down the stairs. yes you pretty much can evacuate the vast majorty of people in the time (3 minutes) it takes to descend 47 floors of staircases. stating it took 5 hours to get some people out in 1993 is very stupid. we don't need to concern ourselves with the sick, injured and the few people with heart problems or a few tourists in wheelchairs, we are talking about the people who worked in a wtc7 which was already half empty and suffered no damage, fire or smoke, half of the people only had to descend 20 floors of stairs, a quarter of people had to descend only 10 floors.
everyone is walking at a slow pace to get out in only 3 minutes, we are not talking about having to run to get out the building in that time. People are not queuing to get tickets at a football match or move through turnstiles, think of a packed train emptying at a busy station and how quickly you can exit the station no matter how thick the crowds are.

Here is a quote from a study done for a 20 story high rise in england
http://www.mace.manchester.ac.uk/project/research/structures/strucfire/CaseStudy/Others/default.htm#fig5

Evacuation
The exits and stairs were sized on the assumption of a phased evacuation. The number and locations were carefully considered so that the local evacuation time is sufficiently low and the travel distances are comparable to prescriptive guidance. The stair locations are distributed diversely and apart from each other to prevent all escape routes being compromised by one incident. In terms of global evacuation, the escape routes were carefully considered and an evacuation time of 58 minutes was calculated. This was introduced to the fire time line.
i think this estimate was probably high.Admittedly I am not an expert in evacuation times but I do not see how you can claim 3 minutes.

i'm saying the distance from the top floor of wtc7 to the bottom using the staircases and a piece of string is 263 meters, at walking pace (5km/hour) it would take 3 minutes. I can't imagine that people would hang around if planes were striking buildings next door. people will pause and ponder when inside a building that's on fire (I know I did when i was inside one), but not when buildings are being attacked by planes. Allowing for congestion, 6 minutes for the bulk of the crowd to get out would seem to be a sensible estimate, but real evidence would be better than assumptions.
