I cannot believe that it took as long as 1hour 40 minutes for someone to scan the 'net in order to come up with concentration camp figures like "Farmer" has. ( Concentration Camps;a British concept, 1st used by British Forces during the Boer Wars), Totally off-topic, therefore I won't even go there.
There were SEVEN (7) buildings in the World Trade Centre complex, ALL were severely damaged, if not destroyed on 9/11.
A gentleman by the name of Gary Stock has gone to great lengths to compile a dossier, not yet complete, of all businesses in the W.T.C. as at 9/11. See following;
Gary has identified over 700 prospects (Businesses), by name. Preliminary research suggests as many as 60 more firms maintained a business presence within the Trade Center complex. Many of these Prospects were so large, that they occupied as many as 10 floors by themselves!!
He has also identified over 240 phone listings present in the WTC complex.
Gary, known as ;Unblinking,has identified over 75 vacant office suites present in the WTC complex, as at 9/11.
Tony,I respect your reply, but,I find it impossible to accept that ANY company having the financial wherewithall to be able to afford office space in ONE of the most, (if not THE most ),prestigious office complexes in the world, would "go to the wall", because of the disaster, Insurances providing.
Keith, definitely NOT a competition of MY making, Guv'nor.
