''The flight numbers of the planes that crashed into the Twin Towers were in fact "11" and "175". Clearly, someone has simply made up this supposed flight number in an attempt to make the spurious claim seem valid.'' Copied from another site
On 11 September are days where the twin towers were flown in. 11 September can also type 11 / 9 - 1 +1 +9 = 11, In September, there are 9 letters and who flew 2 planes into the towers = 9 +2 = 11 Try to go into Word and type in Q33 NY in capitals (it was the name of the first plane that flew into them) endre font to size 48 and type to Wingdings. See what happens. Its kinda hard to translate from Turkish To English so i used google translate.
