White House Drone Incident Exposes Key Security Gap
HughPickens.com writes The Washington Post reports that the intrusion by a recreational drone onto the White House lawn has exposed a security gap at the compound that the Secret Service has spent years studying but has so far been unable to fix. Commercial technology is available that can use a combination of sensitive radar and acoustic trackers to detect small drones, though coming up with an effective way to stop them has been more elusive. "To do something about the problem, you have to find it, you have to track it, you have to identify it and you have to decide what to do with it," says Frederick F. Roggero. "But especially in an urban environment, it would be tough to detect and tough to defeat kinetically without shooting it down and causing collateral damage." Most recreational drones, like the one that crashed Monday, weigh only a few pounds and lack the power to do much harm. Larger models that can carry payloads of up to 30 pounds are available on the market and are expected to become more common. The FAA imposes strict safety regulations on drones flown by government agencies or anyone who operates them for commercial purposes. In contrast, hardly any rules apply to people who fly drones as a hobby, other than FAA guidelines that advise them to keep the aircraft below 400 feet and five miles from an airport. "With the discovery of an unauthorized drone on the White House lawn, the eagle has crash-landed in Washington," says Senator Charles Schumer. "There is no stronger sign that clear FAA guidelines for drones are needed."
Because nobody with bad intentions defies FAA guidelines.
I suspect you could also use an unregulated trebuchet to launch something over a fence, or perhaps an unauthorized weather balloon with a payload to drop something on your neighbor's lawn from altitude. Or a slingshot (although those might be illegal within city limits). The notion of a serious "security gap" is farcical because any reasonably intelligent person could come up with a number of clever ways to outwit fences and exclusion zones.
