Vehicle would be used to secretly drop military teams along coastal

October 9, 2008 (Computerworld) It may sound like something out of a
James Bond movie, but the U.S. military's Defense Advanced Research
Projects Agency is putting out the call for researchers to come up with
a design for a submersible aircraft.

Yup, you read it right. DARPA, a research branch of the U.S. Department
of Defense, is looking for someone to prove that a vehicle can be built
that will fly, as well as maneuver underwater.

The "Flying Sub" from "Voyage to the Bottom of the Sea".
The Flying Sub was launched and recovered from a bay in the forward
section of the Seaview.

referring to. Testor's sold a model of it.)
