I read somewhere a while back where the Russians had developed a super high speed sub that shredded the water in front of it self to fly through the cavitized layer, anybody hear of that one , supposedly went supersonic. In the aircraft world just read where somebody put a prop spinner from a constellation on a DC 3 or similar plane and picked up a good bit of speed and much better engine cooling, whats going on there i wonder, whole nother world of course put eventually all these things tie in together,
