Boeing

The two planes used in the September 11, 2001 terrorist attacks against the Twin Towers were both Boeing 767 wide-body jetliners (American Airlines Flight 11 and United Airline flight 175)

The two hijacked planes could be flown with the same training due to the commong "Boeing key", which made for much better coordination and easier training for al-Qa'ida.

There are a total of 117 seats on the Boeing 717

Boeing

It was founded by William Boeing. He was born in the US and named for his father, a wealthy Swiss engineer who Americanized his name from Wilhelm Böing after emigrating. (" ö " is normally transliterated as "oe" in typefaces and languages that don't support umlauts)

Tidbit: during the design phase of Boeing Corp.'s first passenger jet the numbers sin(45º) and cos(45º) were very frequently used in calculations. The value is approximately 0.7070 and the plane's designation as model 707 derived from that.

In the US on this day in April, 2011, a gallon of jet fuel purchased under a bulk contract costs about $3.25 per gallon.

Why would the wheels spin? They are not connected to the engines. There's no driveshaft or chain or gears to power the wheels. They are free-rolling wheels. The engines push air backward and push the plane forward, but the engines don't drive the landing gear except to raise or lower it if the plane has retractable landing gear.

Do you think the wind should make them spin? Most aircraft have the wheels fully exposed to the air, both the top of the wheel and the bottom of it. So the wind won't blow harder on one side or the other.

There were some experiments with using the air to spin the wheels in preparation for landing. The theory was that this would stop big patches of rubber from being worn off the tires when they (not moving) suddenly hit the runway at high speeds. That kind of stress can sometimes make a tire blow out, which can make the aircraft hard to steer and easy to crash on the runway.

But the problem was that this made landings take up too much runway. Big aircraft actually need that sudden drag on touchdown to help plant them on the pavement and begin lowering their nose.

Nothing. It is simply a model number.

The -100 with the first, business and economy class cabins could hold 366 passengers. In the business/economy configuration it held 452.

7260 nautical miles is the typical longest range

High Bypass turbofan engines use pneumatics (air) for starting the engines.

Air Force One is a Boeing 747 Airplane. The maximum speed of a commercial Boeing 747 is about Mach 0.92. While the accurate information is highly classified, Air Force One probably can't go much faster than that.

No, only the Boeing 747 and Airbus A380 have 2 decks that are flying today.

There is a main spar (lengthwise beam) and a front spar (leading edge) a number of ribs that run front to back of the wing and give the wing surface its shape and usually a spar nearing the training edge of the wing. The wing also has panels that move to bank the aircraft ....... on a small plane just one on each wing but on a high speed aircraft, often two .... one for low speed and one for high speed use. There are additional panels at the rear of each wing called flaps to change the airflow over the wing and thus lift and stalling speed. On some aircraft there are additional panels at the front of the wing that do the same when extended for low speed flight. Finally, there are often lift spoilers on the top of the wing which "spoil" lift when they are raised up ..... they also can act as speed brakes. The wing also holds fuel tanks and all of the necessary control lines to run all this stuff.

The official opposition has 8 provincial seats and 102 federal seat. I hope my answer helps.
