This week, the American intelligence service CIA has released files on research into means to use pigeons and dolphins for espionage purposes. The service investigated this during the Cold War.
In the files you can read how pigeons were trained to fly over specific areas with a camera on their chest, as part of the TACANA project. The CIA also wanted to use the animals to deliver packages to, for example, window frames.
The files include a manual of 75 pages for the use of birds for espionage. Here you can read, among other things, how the animals must be cared for and how a laser can be used to control the animals.
The CIA also wanted to use dolphins to spy on submarines from the Soviet Union. The animals would be able to transport and place sensors via a kind of hood on the snout that could be used to hear where submarines were located. The animals could also carry a camera for photographing the vessels.
The intelligence service adds to the series of publications that none of the techniques investigated have actually been used.
