Pan Am Boing 377 Promotional Film
In 1949, Pan American World Airways adds the Boeing 377 "Stratocruiser" to the fleet.
By 1961, all were replaced by the introduction of the Jet Age.
The Stratocruiser's first flight was on July 8th 1947. Its design was advanced for its day; its innovative features included two passenger decks and a pressurized cabin, a relatively new feature on transport aircraft. It could carry up to 100 passengers on the main deck plus 14 in the lower deck lounge; typical seating was for 63 or 84 passengers or 28 berthed and five seated passengers.
Only 55 Model 377s were built for airlines, along with the single prototype.
On November 29, 1945 Pan American World Airways became the launch customer with the largest commercial aircraft order in history, a $24,500,000 order for 20 Stratocruisers!
