Your numbers are completely wrong. You obviously fail to understand the effects of mass and velocity.
1 knot = 1.15 mph
8 knots = 6.96 mph, 15 knots = 13.04 mph
Do you have any idea what it takes AND how long it takes to stop over 1 million pounds at full steam? Didn't think so...
A. FULL reverse, all propulsion. B. Over 8 miles to come to full stop.
You can bet your skivies that a lot of stuff will "break" in the meantime, if it just happens to be in the way!
