I think the reason why some people couldn't get out was the damage to stairwells above the plane impacts.
People stayed in the south tower after the north tower was hit.
when the south tower was hit, i think that also damaged stairwells, and made it difficult for people to escape.
i know firemen were trying to evacuate people from the buildings, but the towers only stood for so long before they collapsed.
William Rodriguez (Survivor) believes there were explosives of some sort in the sub level basements before the plane hit the north tower which also
took lives (Basement explosions).
MY take on this is that the stairwells were damaged, blocking people from escaping, and that thick smoke made it hard to navigate through the
building.
I don't think anything can be done differently in an event like that. i thought that the buildings would actually hold. i also thought the fire was
burning itself out. but it didn't. the buildings fell so close in between that trying to save people who were trapped would of been next to
impossible, even if we knew the building was going to collapse.
thats my take on it anyway.
