Comet
One sheet vintage advertisement for the
de Havilland Comet jetliner, promoting it as the world's first commercial jet aircraft operated by the British Overseas Airways Corporation (BOAC).
History and Significance
Pioneering Aircraft: The de Havilland Comet was the world's first pressurized commercial jet airliner, marking a new era in aviation history. It first flew on July 27, 1949, and entered commercial service with BOAC on May 2, 1952, with a flight from London to Johannesburg.
Technological Marvel: It was significantly faster, flew higher, and offered a quieter, more comfortable "vibration-free" passenger experience compared to contemporary propeller-driven aircraft. Features included four jet engines buried in the wings, a pressurized cabin, and amenities like a bar and large windows.
Early Success and Tragedies: The Comet was initially a source of national pride for Britain and commercially promising, but within two years of service, a series of catastrophic mid-air breakups occurred in 1954.
Engineering Lessons: Investigations, involving the innovative use of a water tank to test the fuselage for fatigue, revealed that metal fatigue cracks were forming at the corners of the square windows due to the repeated stress of pressurization cycles.
Lasting Impact: The tragic lessons learned from these accidents led to fundamental changes in aircraft design, introducing "fail-safe" design principles and extensive fatigue testing that made subsequent airliners, such as the Boeing 707 and Douglas DC-8, much safer.
Poster Details
Airline: British Overseas Airways Corporation (BOAC).
Year: The poster is generally dated circa the 1950s, around the time the Comet was introduced.
Artwork: It features a cutaway illustration showcasing the passenger cabin with spacious seating and the aircraft's internal layout.
