We kept after the Navy. The pilots and the flight deck crew who saw the UFO had mixed feelings--some were sure that the UFO was a balloon while others were just as sure that it couldn't have been. It was traveling too fast, and although it resembled a balloon in some ways it was far from being identical to the hundreds of balloons that the crew had seen the aerologists launch. We probably wouldn't have tried so hard to get a definite answer to the Mainbrace photos if it hadn't been for the events that took place during the rest of the operation, I explained to the group of ADC officers. The day after the photos had been taken six RAF pilots flying a formation of jet fighters over the North Sea saw something coming from the direction of the Mainbrace fleet. It was a shiny, spherical object, and they couldn't recognize it as anything "friendly" so they took after it. But in a minute or two they lost it. When they neared their base, one of the pilots looked back and saw that the UFO was now following him. He turned but the UFO also turned, and again it outdistanced the Meteor in a matter of minutes. Then on the third consecutive day a UFO showed up near the fleet, this time over Topcliffe Aerodrome in England. A pilot in a Meteor was scrambled and managed to get his jet fairly close to the UFO, close enough to see that the object was "round, silvery, and white" and seemed to "rotate around its vertical axis and sort of wobble." But before he could close in to get a really good look it was gone. It was these sightings, I was told by an RAF exchange intelligence officer in the Pentagon, that caused the RAF to officially recognize the UFO. By the time I'd finished telling about the Mainbrace Sightings, it was after the lunch hour in the club and we were getting some get-the- hell-out-of-here looks from the waiters, who wanted to clean up the dining room. But before I could suggest that we leave, Major Sadowski repeated his original question--the one that started the whole discussion--"Are you holding out on us?" I gave him an unqualified "No." We wanted more positive proof, and until we had it, UFO's would remain unidentified flying objects and no more. The horizontal shaking of heads illustrated some of the group's thinking. We had plans for getting more positive proof, however, and I said that just as soon as we returned to Major Sadowski's office I'd tell them what we contemplated doing. We moved out onto the sidewalk in front of the club and, after discussing a few more sightings, went back into the security area to Sadowski's office and I laid out our plans.
