The continuing study of "UFOs" doesn't surprise me, after all, "UFOs" represent more than the 'extraterrestrial hypothesis' and reported "sightings" could indicate the ramifications of testing our 'black project' aircraft over populated areas. Many investigations of "UFOs" back in the '50s were red herrings that really sought to see if our U2s and such could be seen and appreciated by the casual observer. Then there's the foreign component, if Russia or China were to have a revolutionary design akin to the U2 or the later SR-71 we'd have to take "UFO sightings" in that context seriously. But that's not why I posted this here. The 2004 incident contained in the link is intriguing. The footage has been dismissed by some skeptics as an "artifact" among other things but then one has the testimony of one of the pilots which, unless you missed it, has been blathered over the various organs of our MSM and it goes beyond the 13-yr. video. The gist is he is unaware of anything we had then or now that could account for what he saw.
Thoughts? I was always a "show me the evidence" skeptic regarding "UFOS" as ET aircraft and still am and I'm not about to put an ET sticker on this simply because the 'U' in UFO remains unresolved here but this is the best head-scratcher I've seen since Campeche which, coincidentally was the same year as this Californian incident and Campeche was later debunked by a Mexican pilot replicating the incident, right down to the original flight path. The debunking was only possible because the oil well "flares" that produced the initial Mexican FLIR "UFOs" stuck around. That's not the case this time.
My take? I don't have a clue. I'm going to respect the 'U' here as I usually do with UFOs but keep an open mind that maybe, just maybe, it was horny SOBs from Deneb IV checking out the babes sunbathing on a San Diego beach before our air force had to ruin things for 'em.
