A scientist in a government agency met with the pilot, showed his credentials, unlocked a display case and took out some [UFO] photographs. 'Was it like any of these?' he asked. At the third photo, the pilot recognized the same type of craft he and the othe crew members had seen.
Originally in Major Donald Keyhoe's Flying Saucers: Top Secret. Followed up by NICAP conducting an interview with the pilot to glean further details.
Officer of naval intelligence had a binder holding photographs of UFOs intercepted with what appeared to be printed material.
One photograph seemed a good representation of the UFO we had encountered, and it was noted as being 30 feet in diameter, as I recall. When he gave me that dimension, I told him it was much too small. So he went to another picture that was marked as having a diameter of 100 feet, and asked, "Did this look like what you saw?" As I went through the details of my encounter over the Atlantic a few months earlier, he listened with keen attention, and took copious notes. I recall telling him that the color of the lights on the rim of the object I had seen could best be compared to the color of the electrical discharge of the commutator on an automobile generator when seen in the dark.
