DARPA: your tax-payer dollars hard at work

First it was mine-detecting dolphins and remote-controlled sharks and now it is human cannonballs.
New Scientist magazine reported in May that the Pentagon's cutting-edge research agency, DARPA, is considering a human-launching device that works like a cannon, to blast special-forces troops (and maybe firefighters and police officers) at just the right trajectory so that they land on hard-to-reach locations, such as rooftops. One of the patent application diagrams is pictured below just to give you sense how high-tech the device is.
