Sept 11, 2001 - North Tower disintegration

What is causing the interference with this video feed just as the North Tower started to disintegrate? 🧐

Then something to keep in mind when looking at the "spire" of steel columns - 16 people survived at the bottom of that steel spire between the 2nd and 22nd floor in the stairway B of the building.

Where did all that steel go?

The survivors heard no loud explosions, no flashes of bright light, no molten steel raining on them, they did not go blind or deaf due to light flashes or explosions, they weren’t hit by falling debris - POOF they are gone into a HUGE DUST cloud.
