Not really having time for this stuff now. Basic points were
- It's impossible to know how fast the building would have to be falling to achieve free fall speed, because you don't know it's air resistance etc.
- It's impossible to precisely calculate the actual speed of the falling building
So, even if it's stated it did fall in free fall speed, it's just an approximation that's more or less accurate.
Assuming that it was close to free fall speed, this could very well be because
- Inertia of the falling mass is very high
- Once a wall/beam whatever cracks, theres basically no resistance for until the next floor/beam/whatever
- Imagine a 10m long beam. If it starts to bend until 9m and then breaks in the middle then there is no resistance for the rest of the 9m.
Anyway, those are obviously super simplified concepts, but I'm rather sure it's no worse than saying "free fall is impossible because I think it doesn't sound right".
