.... The guillotine (located at the end of the aerial refueling system) surrounds the hose. Its purpose is to cut, clamp, and release the hose if the tanker aircraft pilot so commands. The reason is that if the hose fails to rewind, the guillotine mechanism allows the tanker aircraft to land without a fuel-laden hose...
