This high resolution photo of N.Y. is the best I've seen so far of the 17 acres where thos towers collapsed.

Thank you for sharing the picture with us, zeusrdx. Welcome to Sciforums while I am at it.

Someone sent the photo to me.

I flew over N.Y. when I was a kid. At that time you needed no radio equipment of any type----you most certainly do now----and the only requirement was that you stayed 1,000 feet above any person. Since there were people in the top story of the Empire State building----the tallest building then----and it was 1,500 feet high then that meant an altitude of at least 2,500 feet;

I flew at 3,000 feet just to be on the safe side but I always like to have a place under me in case I have to land. The planes I flew weren't that good. All those buildings below looked like big spikes sticking up and if I had engine trouble then I imagined getting impaled on one of them and I was glad when I left N.Y. and had a lot of flat land under me again.

Exelent point. I never concidered that at all. In a typical plane how many feet do you drop per 100 feet horizontal movement? I was just wondering with you saying about the minimum flight zone and how far away you can get.

I dont know if this will work but this is a NASA image taken from a satellite over NY. I got it from NASA itself about 3 weeks ago. The original image which started this sectoin was amazing, must have been from a chopper/plane.

Thanks-----I've been using it.
