They will know. If they heard of 9/11 and even saw the events occur, one of these days when those New Yorkers are driving in the Brooklyn Bridge or are about to come back to the city by passing New Jersey, they will see that something is different in the Lower Manhattan skyline. And Hollywood will just spread the news like wildfire as well. Yep, 1 WTC is going to be bigger news when all is said and done. Not news everyone will know,but it will be known more in the future than now.
