The trail I was following was to confirm that the picture was not bogus. I think it will probably be shown to be real and from 1971.
By confirming that you had been in the airport in 1971 or so, and that you recognized the background of the picture, it would have put to rest (at least for me) that the picture could not have been taken in 1961, as many are speculating here.
I do still have questions about the details of the BC.
