I know that @Dejan Corovic has studied this but there is something I've been wondering about: UFOs that disable cars - exactly how? Not Val Johnson or Roy Neary-like incidents where there is some violence involved. I'd add Cash-Landrum to that list as I think the car was running but a bit melted in spots. I'd also note that Lonnie Zamora's car seemed to work OK at the time. I guess some get the big whammy and others don't. Maybe that's the distinction between Earthly objects and ET: the ones stamped Made in USA underneath might burn the crap out of you and make you real sick. I'm talking about turning the car off, leading you away for a probing and then returning you some time later. Exactly how? I remember an interview with JB Alexander talking about nonlethal weapons and he was describing the invasion of Iraq. Easy to turn off power plants, a whoooooole lot harder to fix them. An instant-OFF device would be awfully handy. I know the phenomenon still happens as there was a local report within the past year or two. I've been blabbing about my hobby - old cars. I thought about it and if I were left with a 'classic' vehicle and I had three seconds to disable it how would I do it? Pull the wire marked #1 (negative lead of ignition coil) and the fun machine stops. Pull one of the two marked #2 and the fun machine stops. 50/50 shot, pick the right one. Much easier to understand ignition and fuel delivery on one of these old cars. If you grok that you will grok fuel injection, coil packs and all that used today. Keeping this very simple with old hardware. So here we have Betty & Barney tooling along on their way home - probably have to feed their flying cat. And then beep beep beep, the car went beepbeepbeep. Were they hypnotized and just stopped themselves? Did it kill the ignition and if so, exactly how? I believe the time honored method of stopping a vehicle is a bit less elegant, and it restarting it isn't an option This is what I've been wondering about. All you have to do is suppress current flow on one stinkin' wire and the car stops. Stop suppressing it and it will restart - after you turn the key, it shouldn't just 'come back on'. So I'm asking if anyone knows how to do that from a distance? We've got some engineers here, I'm just a putz with a wrench. A curious one.
