These are some fun facts about Boeing Commercial jetliners.
1. The Boeing 747 (all versions) have traveled an estimated 35 billion statute miles, that is the equavilent of 75,000 trips to the moon and back.
2. The Boeing 767 sucks in enough air during take-off in both of its engines to fill the Goodyear Glimpse in 7 seconds.
3. It took 75,000 engineer drawings to build the first Boeing 747-100.
4. The Boeing 737 is the most popular twin aisle - twin engine jetliner in the world, more than 3,000 have been sold from Boeing, and it has carried the entire world population of 6 billion people and it has traveled more than 25 billion miles.
5. You can fit 45 mid size automobiles on only one wing of a Boeing 747-400.
6. There are approximately 200,000 flights every day around the world.
7. There are 24,000 Boeing 777 flights each month.
8. There are 800 Boeing 777 flights each day.
9. You can fit 6 million golf balls inside of a Boeing 757 freighter.
10. One wind shield or window frame of the Boeing 747-400's cockpit, cost as much as a BMW.
Do you have any interesting fun facts about airplanes?

Here's some facts about the KC-135...
The average passenger car would operate for more than a year on the amount of fuel transferred through the air refueling boom on a Boeing KC-135R Stratotanker in one minute. The fuel system in a Boeing KC-135R is a highly-integrated and interconnected network of fuel lines and nylon fuel cells. The system contains 50 valves and 14 pumps to guide the fuel flow and pass tons of fuel in minutes for aerial refueling work. The total fuel carried on a single flight of a KC-135R Stratotanker would be enough to last an average driver 53 years. Fuel cells in the Boeing KC-135R are made of nylon fabric less than one-sixteenth of an inch thick. A fuel cell weighing 80 pounds will hold seven tons of fuel.
Enough material is contained in the tires of a KC-135 jet tanker-transport's landing gear (eight main gear wheels and two nose wheels) to produce 100 automobile tires.
At 500 m.p.h., each of the four General Electric turbo fan engines on the KC-135R develops 22,000 lbs of thrust, the equivalent of 80 automobile V-8 engines rated at 200 horsepower each. To lubricate its four jet engines, the KC-135R carries a 60-gallon oil supply--enough for 50 cars. The electrical power generated on a single four-jet KC-135R tanker is sufficient to supply all the power needs for 35 average U.S. homes.
The cargo area in the Boeing KC-135R will easily hold a bowling alley with plenty of room left over for a gallery of rooters. The cargo area is almost 11 feet wide, 86 and half feet long, and seven feet high. It would take over 220 average car trunks to equal this space.
During aerial refueling at about 600 miles per hour, the boom operator in the tail of the KC-135R is only 20 feet above the nose of a Boeing B-52 Bomber.
There are 700 electronic tubes in the electronics system of the KC-135R or approximately the number needed to build 50 television sets. The heat generated by these tubes would heat an average five room home. These tubes range in size from sub-miniature one inch in length and one-quarter inch in diameter to tubes nearly a foot long with a five inch diameter.
The KC-135 contains almost 500,000 rivets, which range in cost from 14 cents to $1.50 installed.
Five thousand wires totaling 14 miles in length are needed in the electrical circuits of the KC-135R Stratotanker

I didn't know the 737 was a twin aisle aircraft...

Some other bits of useless information:
1) The original B747's had a centre of gravity problem, and balance issues when on the ground. Boeing found that if they added weight to the engine mounts, the problem could be corrected. The cheapest way of doing this was by filling the mounts with the very heavy and readily available uranium (spent, of course). Due to fears raised in the public forum during the Cold War, this was kept under raps for quite some time.
2) Boeing were skeptical about the strength of the fan blades on the newly developed high-bypass engines designed for the B747. To eliminate this fear, the engine manufacturer (GE I think) invited some Boeing engineers over for coffee and to inspect the blades. Story has it that when the gentlemen had finished their coffee, the host picked up the blade (which the Boeing reps were about to inspect) and smashed the coffee table in half with it. The blade was hardly scratched.
3) Boeing's original B747 test aircraft was designed to turn whilst taxiing by throttling up the engines on one side of the aircraft. This was later redesigned to have a steering mechanism in the undercarriage due to a press van being blown over during an initial taxi testing run. It was thought that it could be too unsafe around airports to turn using engine thrust.
4) Airbus had a massive logistics issue to solve the problem of getting the A380 fuselage sections to Toulouse for assembly. The sections are to be manufactured in Germany, and need to be transported to the assembly facility in Toulouse (similar to the A330/340 and A320 parts). The A380 sections are too big for the A330 transporters, and will be too big to barge along the canal system that runs through Toulouse. Airbus settled on a combination of sea and land to transport the parts, which should make interesting viewing on the highways of Southern France.

Not sure where I got this but here is an air to air vid (it was used as a inside video of some sort for AA), it really gives you an idea of the 777, 757, and a 737 in formation and the respective sizes.
Please be considerate of my bandwidth and download it if you wish to view it multiple times.

I saw that mentioned in Airways too (about the 777's engines being the size of the fuselage of the 727, meaning also the 707/737/757 since they use the same basic fuselage). Is this documented anywhere? Is there a site that lists the dimensions of the GE engines on the 777?

Zobatc: There are 700 electronic tubes in the electronics system of the KC-135R or approximately the number needed to build 50 television sets.
Interesting stuff all around... But this particular detail looks a lot as if the text is a little outdated. Modern TVs have exactly one vacuum tube - if any.
And I´m pretty sure that most of the electronics in the KC-135s will have been converted to transistors or even - gasp! - integrated circuits, by now. Tubes are heavy and need huge amounts of electrical power.
One of the few remaining uses for vacuum tubes today is in some RF power amplifiers. Transistor electronics can even be made EMP resistant by now.
