Calyon Financial, known at the time as Carr Futures, was located on the 92nd floor of the North Tower of the World Trade Center.

With its offices located a floor beneath the impact zone of American Airlines Flight 11, they narrowly escaped the actual plane crash.

All 69 Carr Futures employees who came to work that day perished, with several 911 calls being made from its offices prior to the North Tower’s collapse.

A number of staff found themselves trapped in a conference room when the door jammed shut as a result of the crash.

Those that remained made their way to a smoke-free area of the floor, but by the time the building collapsed at 10:28 AM it had become filled with smoke and flames and conditions there non-survivable.
