ATC
My old man was on duty in air traffic at RAF Wattisham the night of the USAF Bentwaters incident.

He told me, 'something' unexplained definitely entered UK air space and was clearly visible in that area on that occaision.

He also said that Project Blue Book filings were a very regular occurrence, enough to become a joke 'oh, file it to Blue Book'.

Previously, in the early '70's while underground on radar at RAF Northwood, on more than one occaision, duty ATC staff watch 'squadrons of disc shaped contacts' in triangle formation moving at high altitude across London.

I can't corroborate this, because he's dead now, maybe he was having a joke with us, but I'll never forget the Bentwaters flap, he came home quite visibly shocked and full of the mystery 'incident' at the time. I believe that something unusual happened there, unusual enough for intelligent RAF ATC staff to be perplexed, put on alert, file reports etc.
