Did the British invent it? I just assumed that it was the Japanese. That video of the Japanese guy with the rain coat that the article mentions has been on the internet for a few years. Does taking existing technology and using it for something else count as inventing something?
demonstration date doesn't mean invented date. I am sure a lot more engineering went into it before they unvailed it. I wonder how many black ops missions it was used in before they decided to out it? I could see this technology used on fighter jets and Naval ships as well.
