I was living in NYC on September 11, 2001. I happened to be rollerblading that morning toward the World Trade Center and saw the first plane hit the north tower. I was so shaken I took no pictures that day, and frankly was disgusted by some who did.
A few days later, I decided it would be okay. This picture was taken on Broadway headed toward Canal below 8th street in Manhattan. You can see the smoke still smoldering and flowing to the left of the picture toward Brooklyn. Up above where the smoke is originating (the World Trade Center) there is an obvious cross in the sky. This picture was taken on film. After having them developed and glancing through I didn't even see it, regardless of the obviousness of it. I was showing the photos to my uncle and taking more time with them when at the same time we both saw it. Freaked!
I went back to check the negative and it's there. I was so amazed by my find that I tried to share it with major news outlets, no profit intended, but they weren't interested.
