Aerobook: What you didn't know about the Boeing 747

Video from the channel Aviões e Músicas about Boeing 747, linked on its Above Ten Thousand entry. Duration: 7:10. Language: Portuguese. Video type: Documentary.

A trivia video about the Boeing 747 from the Aviões e Músicas channel, tied to its Aerobook reading club, which dedicated its first book to the model.

It recalls that during the design phase an aircraft with two full-length decks along the entire fuselage was studied, and that the cockpit was placed above the passenger deck because the manufacturer was already thinking of using it as a freighter; that is why, according to the video, it is the only commercial aircraft in service where a passenger can sit ahead of the pilots. To transport the space shuttles, NASA chose the 747 over the C-5 Galaxy because it could buy it outright instead of borrowing it from the Air Force.

According to the video, a 747 can maintain flight on two engines; the 747-8's GEnx produces 66,500 pounds of thrust; the 747-8 burns about 11,380 litres per hour, carries about 230,000 litres of fuel, has a range of about 15,000 km, is 76 m long and cruises at Mach 0.86. The 747SP is half a metre taller and about 20 m shorter than the 747-8. The aircraft has 18 tyres, about 274 km of wiring, 8 km of piping and about six million parts. The cockpit crew went from three to two with the 747-400. Boeing built more than 1,500 units and closed sales in 2020, with nine freighters still to be delivered.
