I study UFOs – and I don’t believe the alien hype

As for me, I'm not 100% convinced because I have yet to see again what I myself witnessed in South Orange County, California in the mid 90's. Where is the video with a cam steady on a tripod for perspective that is showing an object zigzagging in the sky? This is what I saw and what was described by every pilot in the encounters.
Another bit that is lacking a complete explanation is the notion that these could be some kind of massless projections or plasma/particle beams. Doesn't this appear more plausible then some kind of super exotic propulsion technology?
