Black Triangle Sighting in London, England on 1975-08-10 13:00:00 – Playing out side and looked up and there it was a tiangle.

Ref 87825 i went back to check on a image that was taken in the 1970's now it has gone cannot find it. this has bothered me for a life time and now the only thing i can relate to is gone and the weird thing my friends cannot recall the event after the sighting am i seeing things that are not there? please check out my previous info.
