One of the greatest feats of American aerospace engineering celebrates 50 years of passenger service this week.
Long before the Boeing 737 Max, there was the Boeing 747, the first quad-jet engine and dual-level passenger aircraft to roam the skies. It's known by many names including Jumbo Jet, Queen of the Skies, and even the Humpback, and is arguably the most recognizable aircraft in the skies.
Boeing conceived the aircraft in the mid-1960s when it was designed to be the next step up from the similarly four-engined and widely popular Boeing 707 passenger jet. With demand for air travel on the rise, the Boeing 747 would offer airlines greater seating capacity, increased range, and extra room for luxuries such as onboard lounges and bars.
Though it took its first flight in 1969, it wouldn't enter service until January 22, 1970, fifty years ago on Wednesday, with Pan American World Airways.
Here's the story of the Boeing 747, the aircraft that would firmly establish America as a leader in aircraft manufacturing for decades to come.

Shortly after the Boeing 707 rushed the world into the jet age, airlines were already looking for bigger and better aircraft, including Pan American and its CEO, Juan Trippe.
Fresh off the heels of competing for a government contract for a widebody military transport, Boeing used its newfound knowledge in the field to lay the foundation for its newest project, according to the manufacturer.

Over 50,000 employees working on the project at a new assembly plant in Everett, Washington, according to Boeing, that was so large it was given its own zip code. They were called "The Incredibles" and lead by veteran Joe Sutter.

The aircraft they produced would be the Boeing 747-100, the first variant of a new aircraft that featured four engines and two-levels, the first jet aircraft of its kind.
The flying public had never seen anything like it before, with jet aircraft only recently coming to prominence just over a decade prior.
Its first flight flew in the early morning hours of January 22, 1969, from New York to London operated by Pan Am, inaugurating a new era for air travel.
The aircraft was seen as a status symbol for airlines, with the extra space allowing for additional luxuries and extravagances on some airlines.
Most airlines of the time including Pan Am and Qantas used their upper decks for as bars, lounges, or restaurants.
They were a glamorous place to steal away to while flying high in an enclosed tube.
It was the most exclusive club in the sky.
The aircraft allowed airlines to fly more people further, with normal passenger capacity for the aircraft growing to upwards of 300 seats in later variants.
The range of the aircraft gradually increased over the years with the -400 variant - one of its more modern bestsellers - having the ability to fly over 7,000 nautical miles, enough to connect New York with nearly every continent with a nonstop flight.
