Re: B-25 Crash into the Empire State Building (28 July 1945)
I'll give a little more detail into my answer this time. I put red lines on the ESB in the picture to point out one major difference that some seem to overlook. The building continued to get thinner the higher it went, and as you can imagine, that means less weight above where the plane impacted. The ESB had interconnecting collums throughout the building, where as the twin towers had a tube within a tube structer, meaning the inner core and outer walls supported the weight together, and were joined together by floor spans that were welded, bolted, had sheertmetal spans laid down from end to end to make sure there were no open holes, and then had 4 inches of concrete poured on top of that. They made it that way to maximize floor space, and inturn increase their revenue. It was very strong, and worked very well under normal conditions, but a 767 slamming into them at over 400 mph was in no regaurd normal. I'll add this link too, check it out if you can, it is very simple and does a very god job of explaining it. http://www.lohud.com/graphics/911/fl...owersfell.html |

Re: B-25 Crash into the Empire State Building (28 July 1945)
The B-25 is actually a pretty small plane compared to any regular passenger plane now. But it is really small compared to the 767 that hit the WTC B-25 Max. takeoff weight: 35,000 lb (15,910 kg) Maximum speed: 272 mph (237 kn, 438 km/h) Length: 52 ft 11 in (16.13 m) Wingspan: 67 ft 7 in (20.60 m) Height: 16 ft 4 in (4.98 m) Fuel: In this case not much (probably 220lbs/100kg worth) 767-400 (From 9/11) Max. takeoff weight: 229,000 lb (103,870 kg) almost 10x Maximum Cruising Speed: 493 knots, 567 mph, 913 km/h (Almost 2x) Length 201 ft 4 in (61.4 m) (Almost 4x) Wingspan 170 ft 4 in (51.9 m) (Almost 3x) And the biggest difference Fuel 24,140 US gal (91,400 L)!! Add that all up and I'm not a mathematician, but even I can figure out how much more damage the planes from 9/11 could do than a dry B-25... |

Re: B-25 Crash into the Empire State Building (28 July 1945)
B-25 weighed 20,300 pounds w/o fuel and up to 27,000 with armaments. Weight of a 767 is 336,000 or 380,000 pounds depending on type. the B-25 only carried about 975 gallons of fuel. Also, the speed was much less. The B-25 was trying to pick it's way around the buildings and get out of trouble and hit at an oblique angle. It was angling up to try and clear the building.
