Thanks Martin and you also Peter for bringing out these points. One thing to each of you - Peter, I've read about your idea for a passive system and for what little it's worth I agree 100% it would do the job. Martin, the first time I saw some of your posts here in recent years, I looked through my 200+ UFO books and grabbed my copy of UFOs 1947-1987 and saw that "Yep, it's _that_ Martin Shough!" I remembered your article (Radar And The UFO I think), and I'm honored to converse with you. (That is you, right?) The wonders of the Internet age... So - these shortcomings you point out, Martin. I guess a question I'd ask you is, given NEXRAD shortcomings, if Dr. Fries and his crew deem the system worthy of monitoring for meteor re- entries, might we on the UFO side also _potentially_ expect to see anomalous returns of interest? Not that I myself have the time, I've got all I can handle in GA! But how valuable, or not, do you think it might be if Somebody in UFO research somewhere, can keep up with it? Call this question 1. Question 2 might be, what about in UFO case work? For UFO sightings I've pitched within MUFON the idea of looking at NEXRAD (and I'm not the first) (but lately, might be!) because the data are free & fast & easy to get. And, can be ordered for dates say 1, 6 or 12 months back. Obviously the short sighting durations versus NEXRAD's 6-minute-apart or 10-minute-apart updates are a problem, but we do have long-duration sightings and on some of them (multiple witnesses, bright colored lights, substantial altitude & stationary behavior) I might argue that a _lack_ of a return is telling us something (i.e. it really ought to be there). So - what do you think of its value when investigating selected cases that have, say, long durations and are high up enough to be above ground clutter? The technical material you can find online says NEXRAD can and does detect birds, insect swarms, aircraft, and so on. Why not UFOs? I'm travelling next week on business and likely can't reply, but I'd be delighted to hear what you think on these points. You also, Peter... Listen to 'Strange Days...
