Death Ray

I was pleased today to see my childhood vision of the future coming one step closer today. A laser system for shooting down aircraft has been demonstrated. A lot of my reading as a teenager was of books where people were torn apart by ravening death rays, so this is way overdue. Death rays existed before the laser, of course (the Martians in War of the Worlds had them), but that invention did give a focus to hopes of futuristic death. A pity then that the main uses of the laser turned out to be stuff like survey equipment and playing CDs.

I notice that the artist's representation can't resist the cliche of a brightly coloured beam linking the laser to its target. To be fair though, the conscientious BBC journalist did note that this is rubbish.

I bet the range is, and will remain, rather short. You just can't get round that inverse square law.
