Do you seriously think the Mossad would take a chance on destroying the WTC and then alert this shipping company to move out? Do you really think they'd be that stupid? Quite frankly, this has far less credibility than those rumors circulated in the Arab world that thousands of Jews were alerted not to go to work on 9-11. Healthy scepticsm is one thing, outright paranoia is another.
BTW, the Bilderburgers ate the cookies, the Illuminati drank the milk and I think the Queen of England stole the "rose colored glasses".
