Empire State Building vs. World Trade Center (South Tower).

Planes

about 20,000 lbs.

less streamlined.

about 225 mph.

Not sure what it was made of.

Most likely aluminum.

about 450,000 lbs.

more streamlined.

about 586 mph.

Made of aluminum.

Buildings

weighs 365,000 tons.

1,250 feet tall.

Made of mostly concrete,glass, and limestone.

913 feet above ground.

73% of total height.

crash was an accident.

weighed 750,000 tons

was 1,362 feet tall.

was mostly made of steel, glass, and iron.

1,176 ft. above the ground.

79% of total height.

crash was on purpose.

Weather

Misty,Foggy

40% sky was cloudy

b-25 mitchell weighs 4.4% of the 767

Fire and heat played no part in WTC collapse.

NOVA and the Minerals, Metal, and Materials Society explain that the fires did not play a role in the collapse.

WTC crash happened 1,176 ft up which is 79% of the height of the WTC.

ESB crash happened 913 ft up, which is 73% of the

height of the ESB

A building built with sturdier materials than the other, not to mention that it got hit by a smaller plane at a lower speed with a less streamlined shape and was a complete accident gives the Empire State Building almost every possible advantage in surviving the crash.

Thick Question

Why did a plane crash cause less

damage to the Empire State Building

(ESB) than to the World Trade Center

(WTC)?

Thin Questions:

What type of planes were the planes?

What speed were the planes flying at?

What was the weight of each plane?

Was the crash on purpose or an accident?

What materials were the planes and buildings made of?

What was the weather on each day?

Fact!

WORK!

We did not mention fuel capacity because that jet fuel was spent fueling fires that did not affect the collapse.
