This file, held under a National Aeronautics and Space Administration title, contains an English translation of the 1999 COMETA report "UFOs and Defense: What Should We Prepare For?", produced by a French association of former IHEDN auditors and first published in a special issue of VSD. It opens with a 2001 letter from Carol Rosin arranging a meeting. The report covers pilot testimonies, close encounters in France, GEPAN/SEPRA research and defense implications. Attached material includes a Leslie Kean article, a NARCAP description and a news item about a UFO at Barnaul airport.
From the source: Release of 2026-05-08 Incident: N/A. Released with redactions. NARA Record Group 255, catalogue id 413270. This file contains an independent report on UFOs written by the French association COMETA (previously published in the French magazine VDS in 1999), which details the results of a study by the Institute of Higher Studies for National Defence. The file also includes a letter from Carol Rosin in which she notes that she was spokesperson for von Braun during the last years of his life.
Ioccurred every 600 microseconds. The radar~ scanned the horizon four times per minute. Three other officers (pilot, copilot, navigator) were in the cockpit and, as a result, Icould themselves see out of the aircraft. The six officers were questioned by MacDonald in 1969. They related that: - The first incident took place above Mississippi, probably at around 09302 (0330 local 1·time}, when the aircraft, going back to the north from the GulfofMexico, was approaching the coast a little to the east of the Mississippi delta, flying at Mach 0.75. Captain MacClure detected on his screen a blip corresponding to a pulsed microwave Isource located behind and to the right of the RB-47 (at "S o'clock") that rapidly passed the aircraft and turned around it, departing again on its left in the other direction (between "6 o'clock and 9 o'clock"). The source was therefore airborne and supersonic. MacClure 1·noted the characteristics of the signal: they were those ofthe aforementioned ground radar stations, with the exception of the length of the pulses, which were 2 microseconds. He did not report this incident immediately, thinking that it was perhaps ·a malfunction ofthe Ielectronics. As Klass writes, at the time there were no supersonic aircraft either in the United States or in the USSR large enough to transport a radar, the signal from which possessed the characteristics that were observed. - The following incident occurred at 101OZ in Louisiana, when Commander Chase, pilot, and Captain MacCoyd, copilot, saw an intense bluish-white light aim at the aircraft from " 11 o ' clock," then jump from their left to their right and disappear while it was at "2 o'clock." Klass showed that this object was perhaps a meteorite the trajectory of which caused an optical illusion, but, at the time, Chase and MacCoyd wondered whether it wasn't a UFO. Hearing them, MacClure remembered his prior detection and looked for a signal of the same type. - He found this signal at 10302, which was identical to the previous one and, perhaps by coincidence, came from "2 o'clock." This signal was confirmed by Captain 1·Provenzano, whose detector was itself also able to operate at around 3000 MHz. It could not have been the signal from a fixed radar, because its ''2 o' clock" direction remained unchanged when the aircraft followed its route to the west for several minutes. The Iaircraft entered Texas, then came within range of the "Utah" radar [center] located near Dallas. The crew reported to Utah, which detected both the aircraft and an object maintaining a constant distance of 18 km from it. I- At 10392, still in Texas, Commander Chase perceived a large red light, which he estimated was moving 1500 m below the aircraft at approximately "2 o'clock." The aircraft was flying at an altitude of 10,500 m, and the weather was perfectly clear. tAlthough the commander was not able to determine either the shape or the size of the object, he had the distinct impression that the light was emanating from the top of the object. IAt 10402, he received authorization to pursue this object and notified Utah. He slowed down, then accelerated; Utah informed him that the object was mirroring his movements, all the while maintaining a constant distance of 18 km. I- At 10422, Chase accelerated and saw the red object tum to the right in the direction of Dallas; this was confirmed by MacClure. - At around 10502, a little to the west of Dallas, the object stopped and simultaneously Idisappeared from the view of the radar(~) (Utah and the onboard radar that had just detected the object when the RB-47 had approached it) and from MacClure's screen (the disappearance ofan object from a radar screen is less surprising nowadays; it calls to mind Ithe active stealth technologies currently in development if not in operation). The aircraft then banked to the left. MacClure picked up a signal that was perhaps the one from Utah. I I
