The CIA has a fabulous photostream featuring pictures and descriptions of some incredible spy tools. Most are obviously a little old-fashioned. But check out the "Letter Removal Device." That looks like something that might still come in handy. And which New Yorker couldn't use a Pigeon Camera? Below are a few of my other favorites . . .
Above: Charlie the Robot Fish, which "contains a pressure hull, ballast system, and communications system in the body and a propulsion system in the tail. It is controlled by a wireless line-of-sight radio handset."
Above: The Belly Buster Drill from the 1950s and early 1960s. "It would drill holes into masonry for implanting audio devices. After assembly, the base of the drill was held firmly against the stomach while the handle was cranked manually. This kit came with several drill bits and accessories."
Above: Love this one. It's the Seismic Intruder Detection Device, which was "designed to blend in with the terrain. It can detect movement of people, animals, or objects up to 300 meters away. The device is powered by tiny power cells and has a built-in antenna. Its transmitter relays data from the device findings via coded impulses." Keep your comments respectable, readers.
