>they are made out steel, which is unaffected by conventional fires
uhh steel is the one that's susceptible to fire, did you mean concrete?
concrete works well against fire
steel weakens significantly, which is the root cause for why WTC 1 and 2 collapsed
not a surprise to find out weakened steel was the cause behind WTC 7, makes sense
all 3 buildings relied heavily upon their steel

also don't cherry pick angles
other angles show it toppling and buckling
and in your gif you forgot to include the part before, where the interior collapses
you only show the empty exterior shell collapsing, it's much easier for that to reach free fall speed
and it only fell at that speed for a couple seconds before slowing down

yeah nothing seems off about this
