The story...

Zim-American Israeli Shipping Co. Inc. used to have offices in the World Trade Center, but they cleared out just two weeks before the attack. What did they know?

Our take...

Some sites like to make this sound as though Zim left in a hurry, perhaps unexpectedly, and it’s claimed they broke their lease. No source is ever provided for this suggestion, though, and other accounts say not.

...their rental lease contract with the Port Authority expired on September 1. Still, Zim Israel had kept a small office behind in the World Trade Center, an office which consisted of their computer shipping tracking equipment. All of the computers were destroyed in the 9/11 attack and Zim's operations were actually down for a short period. Why would Israel have opened their merchant marine fleet to such vulnerability?

Hmm, some Zim employees were in the towers when the attacks happened? Not what you’d expect from anyone who knows what’s going to happen. That’s accepted by other sites, too.

More than 200 workers had just been moved out; about 10 are still in the building making final moving arrangements on 9/11, but escape alive. [Jerusalem Post, 9/13/01, Journal of Commerce, 10/18/01]

And the “sudden” move? Not so sudden. The President of the company said “initial planning for this move began as part of a Go Forward Plan initiated almost two years ago”. It had been announced the previous April that they were going to relocate to Norfolk, Virginia, in April 2001.

"October 18th 2001
NORFOLK - Governor Jim Gilmore today announced that Zim-American Israeli Shipping Co., Inc. has officially opened its United States headquarters in Norfolk’s Lake Wright Executive Park. Zim-American Israeli Shipping Co. announced in April that it would invest $6.2 million to locate in the new building and would hire 235 people to work in this facility. The firm completed its move to Norfolk from New York City’s World Trade Center two weeks before the September 11th terrorist attacks"

If this still seems like “too much of a coincidence”, then let’s put it in perspective:

Built in 1970, the World Trade Center housed more than 430 companies from 28 countries
http://edition.cnn.com/SPECIALS/2001/trade.center/tenants1.html

That was 430+ companies in buildings 1, 2, 4, 5, 6 and 7. If, just hypothetically, 5% of the companies moved out every year, that would be 21 in total, or about one every two and a half weeks. And having someone move out two weeks before any given date would be no surprise at all. We’ve no idea if that 5% figure is accurate, but that’s the kind of issue that needs to be considered before we decide how much of a “coincidence” this really is.

Of course there are those who will say it’s odd that it’s an Israeli company, given the missing “4,000 workers” or the Odigo message. But then that only raises another question. If If Israel supposedly knew of the attacks in advance, and issued these warnings, then why did they forget to warn the Israeli company ClearForest? 

Sigal Srur, ClearForest's director of human resources, said that four or five of the company's 18 workers were in the building when it was hit. "They got out at the last minute, and two who were lightly injured with scrapes have already been discharged from the hospital," she said from the company's Or Yehuda R&D offices.

Odd, really, because this is starting to look very inconsistent. Zim had enough “forewarning” to move out months in advance, Odigo got a message sent to the wrong place that didn’t identify the target, only a couple of hours before the attacks, and ClearForest didn’t get a warning at all. Clear proof of Israeli foreknowledge? We don’t think so.
