Very good, Pt.2,under same conditions as the Pt.1, you now have an object(a plane if we had one)flying at the speed of light, which is 186,282 miles per second. 572 miles per hour, set against 186,282 miles per second. Thought it time to share this with the world, starting with our sub culture, my way of paying back. will be very interested in answers, there were several high placed field people who didn't get it right, I think there is a lot of intelligence in our sphere. will answer from profile. Luck
