AI Thread Summary
The discussion revolves around the phenomenon of the moon being mistaken for unidentified flying objects (UFOs), particularly in the context of radar systems like the Ballistic Missile Early Warning System (BMEWS). When BMEWS was first operational, radar signals reflecting off the moon were often misinterpreted as potential missile threats. This confusion persisted for nearly four decades, highlighting the challenges of distinguishing between genuine threats and false alarms.Participants recall instances where natural occurrences, such as flocks of geese, were similarly misidentified as missile attacks, leading to unnecessary military responses. The conversation touches on the technical aspects of radar systems, including issues with equipment like Klystrons and the experiences of operators in control rooms. There is a mention of a physics professor who documented various false alarms related to missile launches, emphasizing the importance of accurate identification in military operations. The discussion also hints at concerns regarding automatic launch systems and the implications of misinterpretation in high-stakes scenarios.

When the old BMEWS sites at Thule and Clear first came on line, radar signals bouncing off the Moon were interpreted as unidentified objects that were possibly incoming missiles. They used the same basic work around to eliminate the false returns for the nearly 40 years that system was in operation.

BMEWS officially stood for Ballistic Missile Early Warning System, but the more popular interpretation was Bewildered Men Existing Without Sex.

I'm not sure about this guy's explanations of the bangs that would sound when one of the transmitters went. We never had a capacitor blow while I was up there, but maybe they replaced the original ones. The Klystrons tended to blow fairly often and they sounded just like a gunshot, which was good in a way. The console operators knew to check their consoles immediately to figure out which transmitter blew.

We didn't have static electricity problems in the control rooms by time I was up there, either. On the other hand, the static electricity in the dorm rooms was horrible.

Since there is obviously no mystery, moved to GD.
 
I remember also back from the old days when a flock of geese was interpreted by NORAD as an incoming missile attack. I can't recall whether or not they realized their error before scrambling interceptors.
 
I once had a physics professor that had a list of near launches of nukes caused by things like flocks of birds. IIRC, there were about twenty examples between the 60s and 80s.

He was part of a movement to stop the deployment of systems that would automatically launch on detection. I don't know if these systems were even installed.
 
Which 'he' do you refer to?

So the guy was unable to identify the moon, and then confused it with an UFO? :-p

Sorry, Ivan. Since that came on the heels of my post, where I was scared garbageless about W having his finger on the button, I didn't realize that you were still referring to the prof.
