Leslie was in her office on the 36th floor of Tower One.

At 8:43 a.m., she was working out a solution with her assistant when the building shook violently.

The building swayed back and forth slowly for a few seconds and then stopped.

Leslie says, "From that precise second, time was both accelerated and suspended.

" Loud bangs resonated from the north side of the office.

The floor was in full tilt.

Everything in the office flew right out the windows.

Panic was instantaneous, and a mad dash toward the exit stairs began."
