UFOs ‘Roam our skies’ Says Former US Air Force Intelligence Officer ~ Prince Phillip invited pilot and crew to dine and discuss encounter

In a written submission to the hearing he described the experience as follows:
“They called out your miles apart, 60, and 40. At about 30 miles my APS-23 Radar picked up the hovering UFO directly ahead.
“It was an exceptionally large radar return reminding me of a large bridge or ship. This craft was bigger than anything I had seen in the air before. It reminded me of the radar return from the Brooklyn Bridge 6,000 feet or the Firth of Forth Bridge in Scotland (8,300) feet, over a mile long. 
“The return was sharp and solid as compared to the fuzziness of a rain cloud. I felt this craft must be made of steel or strong metal. We were doing around 425 mph as we approached to about 10 miles, when the UFO apparently realized we were intercepting,” he said.
“It was a dark night; we could only see a series of dim lights directly ahead similar to a cruise ship at sea. Now only five miles separated us. Suddenly the UFO seemed to come alive, the lights brightened immensely and the UFO accelerated in a launch similar to the Space Shuttle taking off at night. 
“We saw much brighter lights and fantastic acceleration as it climbed almost straight up and suddenly it was gone. These huge craft I learned are called mother ships, because like an aircraft carrier they carry smaller disc craft.
“We asked London Control, if they had any rocket launches in the area. London Control seemed as disappointed as we were. The controller said, “There are no rocket launches in that area, thank you for the intercept, you are now cleared to return to your mission.” 
Royal AttentionFiler said the incident did not gain vast attention although he did record it in his navigator’s log and it was mentioned the next day in operations. A few weeks later, however, he and his crew received an invitation to dine with Prince Phillip, Duke of Edinburgh, who had expressed an interest in their experience. 
“About seven of us sat around a table discussing UFOs. Prince Phillip was very personable and friendly. He was very interested in our intercept and we assume he had also been briefed by London Control because the U.S. Air Force had no apparent interest,” he said in his written testimonial.
When he asked the royal consort of Queen Elizabeth II why he was interested he said Prince Phillip replied: “My uncle who raised me, Earl Mountbatten had seen UFOs close up while in the Navy.” 
Filer said Prince Phillip told him he had debriefed aircrews who intercepted UFOs “on many occasions.” 
Filer said he has researched the topic of UFOs over many years and now believes that extraterrestrials have been visiting planet earth for thousands of years.
He referred to archaeological structures carved in the soil called cursors, which are found throughout England. He believes they resemble the reported shape of mother ship UFOs.
“This complex at Stonehenge and Silbury Hill in England, may in fact represent visitation by an alien race in the distant past,” he said.
Filer had another experience with an extraterrestrial craft while in the U.S. Air Force according to organizers of the Citizen Disclosure hearing but he did not discuss it at the event. He is now a regional director of the Mutual UFO Network (MUFON), a nonprofit volunteer organization which was established in 1969 to record and study UFOs. He also produces a weekly UFO newsletter called Filer’s File.
