The Boeing 377 Stratocruiser was the commercial version of the C-97 Stratofreighter. The two-
level 377 was pressurized and could accommodate 50 to 100 passengers. On long flights the
aircraft could accommodate 28 upper and lower bunk units. This led to the aircraft being referred
to as the “Flying Hotel”. The 377 was larger and could fly further than the Constellation or the
DC-6 but the engines and complexity of the aircraft proved to be too costly to operate bringing
production to an end in 1950.

Transocean Airlines N403Q was c/n 15946 and ordered by SILA (Swedish Intercontinental Airline
Company) on April 18, 1948. Due to an airline merger the order was transferred to BOAC who
took delivery on December 16, 1949 as G-ALSD and named RMA Cassiopeia. On September 7,
1958 the aircraft was sold to Transocean Airlines registered as N85Q. The aircraft was converted
to a 40 passenger luxury airliner and re-registered as N403Q in October 1959. In September
1960 the plane was sold to Aero Spacelines for parts for their Guppy program.
