Here's a video of an EgyptAir 737-800 being built from scratch. It shows the parts departing from Boeing Field in Seattle on a ferry flight to its home operating base in Cairo.
The Boeing 737-800 is one of three versions produced. The Boeing 737-100/-200, powered by Pratt & Whitney JT8D engines, the Boeing 737-300/-400/-500, introducing high bypass ratio CFM56 turbofans and more advanced avionics, and the Next Generation Boeing 737-600/-700/-800, delivered to the first customer in December 1997.
This achieved a record 1,500 deliveries within six years. Next Generation Boeing 737s feature more efficient CFM56 engines, a new wing, larger fin and all-new flight deck.
The Boeing 737 has been sold to more than 540 airlines and on average there are 1,250 in the air at any one time.
