UPDATE Wed, Dec 21st: In today's Newsday you can read Wrong-way flag yanked at WTC site. The flag was displayed backwards on the beam. Thankfully, there are enough Americans who love the flag to have noticed this disgraceful faux pas. Sadly, I missed it.
If you click on the image below, you can see the US Flag on the beam as it appeared yesterday.
The first beam of the "Freedom Tower" was erected at ground zero in NYC consisting of thousands of signatures. It will be completed by 2011.
