Now there’s a conspiracy. That’s a big call man.
We were deplorable for most of that game and it could have been anyone’s right up to that Josh Thomas goal.
Does Varcoe play? Poor family and friends.
Not meant to be the Pies year!!!
Back to thread,
If the steel structure of the towers which allegedly collapsed due to the impact as steel melts at 2500 Celsius (could be wrong) and the actual temperature reached 1500 degree Celsius (again could be wrong as I can’t recall exactly what the figures were and I’m about to see a client so not googling), wouldn’t the building have collapsed by falling on the side of impact, rather than the perfect pancake collapse?
It’s probably been explained, but I switch off notifications to this thread when it starts it’s merry go round, so there’s a high probability I’ve missed it.
Structural steel loses half its strength at 600 degrees celsius. Fires reached 1000 degrees in both WTC 1 / 2 and burned for 90-100 mins. With the damaged columns causes by the impact and the remaining columns affected by fire a global collapse ensued. Some of the weakened outer perimeter columns also pulled on some inner columns speeding up the collapse.
This inward bowing is actually visible on some NYPD air wing videos of the towers just prior to the collapse. Look it up on YouTube.
