This is a remarkable look at what goes in to making a Boeing 777. In four minutes.
Much of the 777 is outsourced as entire sections, such as the vertical stabilizer, so a lot of what you see are the parts coming in off the docks and being maneuvered into Boeing’s massive hangar for final construction. Especially impressive is the painting facility, shown near the end of the video. A fully painted 777 has 475 pounds of paint on it. (Which is why American Airlines doesn’t paint their planes, as that’s a lot of weight to be flying around over the life of an aircraft for no reason other than looks.)
