Boeing produces over FORTY B-737 airplanes a month!
That's about one every 18 hours!
How do they do it? A train arrives with the fuselage (main body section) in the morning. That starts a moving production line process that results in a completed plane, ready for flight testing, about 18 hours later.
This 3 1⁄2 minute video that shows the entire process, is truly fascinating.
