Regarding the supposed F-16 pilot's "sighting" of a UFO, we have to remember that the F-16 pilot did not actually see a UFO at all. When Marc Hallet of
"The Skeptic Report" actually interviewed the pilot and some of his fellow flyers, it was clear that they were all quite amused at the UFO hypothesis. If SOBEPS (Société Belge D'étude des Phénomènes Spatiaux, a Belgian UFO investigation group) had not turned this into a UFO flap, these alleged mysterious radar returns would have been labeled for what they were, a well understood phenomenon known as
“dot angels”, a common occurrence where a back-scattered radar return is received from dry roll convection in a clear air atmospheric boundary layer. This radar phenomenon is also known as
"Bragg Scattering".
Furthermore, the sudden apparent acceleration of a
"dot angel" radar return is also a well known phenomenon. It happens when there are sudden changes in the convection architecture, the airmass from which the area where the return is coming will suddenly dissipate and the radar return will appear to accelerate dramatically and diminish suddenly. Its difficult to visualize how this happens, but the simplest analogy is a wave breaking on a beach. A wave comes towards the beach at, say 10 kph, but when it starts to break, the break point can shoot along the top of the wave at many times the speed of the wave, as much as 80 - 100 kph.
