The story...

A number of business leaders who would normally have been in the World Trade Center, were instead at a meeting hosted by Warren Buffett on September 11th at Offutt Air Force Base in Omaha, Nebraska. That group included Anne Tatlock, CEO of Fiduciary Trust Inc., a company that occupied five floors on or above the 90th floor of the South Tower.

Our take...

This sounds very suspect, right? A selected group from the WTC are removed from the scene, just in time, by the US military. Unfortunately that’s not the case at all.

Issue number one is the people who were at Offutt. The claim says “a number of business leaders who would normally have been in the WTC”, but fails to name anyone but Tatlock. Why? We think the most likely explanation is that she’s the only one who was normally based in the WTC, and we’ve yet to see anyone else named.

And issue number two is the reason they were there. Some sites try to make this mysterious by saying it was a meeting, or make it seem business-only by calling it a "conference". Neither are correct. This is what was actually going on.

WARREN BUFFET'S CHARITY CLASSIC Sept. 11, an event that draws celebrities, professional athletes and CEOs to Omaha, Nebraska will be the last. It has raised nearly $9 million for four charities in its nine-year run while bringing to the event such notables as composer Marvin Hamlisch, investing guru Peter Lynch of Fidelity Management, then-Securities and Exchange Commission Chairman Arthur Levitt and actor Chuck Norris. Another $1 million is expected to be raised at the last of the one-day Classics, scheduled for Sept. 11...

This suggests Tatlock wasn't part of some small group saved at the last minute. In fact, as "celebrities" and "professional athletes" tend to have busy calendars, the date is likely to have been arranged many months earlier. It's part of the job of CEOs to go around and attend such things, representing their company, and there's no surprise that someone at the WTC had business elsewhere on 9/11.
