content: HMS Sussex was a Country Class heavy cruiser displacing 13k tons fully loaded with 4.5 inches belt armor, presumably rolled homogeneous armor (conforming to 145 ksi), which is a strip around the ship of thicker steel at the water line running several feet up the side, the very location where the plane hit it. For a 14 inch wide strip running the height of the ships 21 ft draft, gives the belt a flexural capacity of 9248 kip-in. The plane which struck the Sussex amidships was a Mitsubishi Ki-51, a light dive bomber weighing 6100 lbs carrying 551 lb of explosives in the kamikaze loading configuration. Traveling at it's maximum speed of 269 mph, the plane would have 12819748 J of energy, with the explosive payload being equivalent to 1153017613 J for a total of 1.16*10^9 J of energy. Compare this to WTC1 and 2 which were comprised primarily of tubular columns fabricated out of 14x14 A36 (36k ksi) structural steel plates, at the point of impact were 1/4" to 1/2" inch thick. Per the American Institute of Steel Construction: Steel Construction Manual LRFD 3rd Edition; this gives each 20 ft column a flexural capacity of 4017 kip-in., less than half the strength of the Sussex. The Boeing 707s which struck WTC 1 and 2 weighed approximately 272126 lb laden and were flying at approximately 600 mph, giving the planes 4.43*10^8 J of energy, 4 times the total energy of the explosive laden Ki-51. Not only is the crusier twice as strong but it was hit with 1/4 the payload. But do go on with your smarmy, snarky attitude in spite of your complete lack of basic physics and engineering knowledge.
