[h3] Weird booms across the US [/h3] A series of strange window-rattling booms or rumbles have been heard and felt in recent months in Alabama, North Carolina, Mississippi, and, on April 4, in San Diego County. The latest disturbance was said to have set off car alarms, caused waves in a backyard pool, and shook double steel garage doors. It wasn't an earthquake. And the Federal Aviation Administration has no record of planes breaking the sound barrier at the time. Apparently, nobody seems to know what the hell caused the disturbance. From the San Diego Union-Tribune: [blockquote]By noon on the day of the incident, The San Diego Union-Tribune was being inundated with e-mails from people wondering what could have caused the strange tremors.
"My garage door is double steel and it weighs about 500 lbs.," a man in University City wrote. "It was rattling back and forth like a leaf in the wind for about 3 or 4 seconds."
A Mission Beach resident compared the sensation to "somewhere in between an explosion and an earthquake." A woman in Carmel Valley noted that the rattling was very distressing to her cats...
Among bloggers and Web-based conspiracy theorists, one of the leading explanations for the San Diego disturbance is that the military is testing a top-secret spy plane called the Aurora, which supposedly can travel several times the speed of sound.
"Sir, I've never even heard of that plane before," an Air Force spokeswoman in Virginia responded when asked about the possibility.
Even UFO experts are baffled by what happened in San Diego. Asked whether a flying saucer might have caused such an event, Peter Davenport of the Seattle-based National UFO Reporting Center said, "Probably not."
"UFOs almost never generate sonic booms or shock waves," he added. "They accelerate so rapidly that they leave a vacuum in the sky, much the way lightning does." [/blockquote][a href="vny!://www.signonsandiego.com/news/northcounty/20060423-9999-1n23bigboom.html"]Link[/a]
