"Working at the Federal Building [U.S. Post Office], it was our job to hang swing stage scaffolds from the 7th floor setback roof... While moving one of these 7 foot pieces of aluminum I noticed what looked like an airplane part. I picked it up and it had a serial number on it and something in writing "hydraulic piston"... About a half hour later, the Postal Investigator and an FBI Agent came up to the setback roof. I was asked where exactly did I find it and not to remove anything else, especially anything spray painted in yellow paint... I had my camera and headed for the upper roof and I couldn't believe what I saw. There was a large piece of a landing gear and pieces of airplane parts all over the roof. I took many pictures and quickly left the roof... I'm a construction worker and have almost no knowledge of photography, my pictures are real and authentic and have never been altered in any way. - Louis" -
