The first Jumbo 747 was born on the drawing boards in 1969. And flown for the first time in 1970....it was an aircraft which was rejected by the directors of Boeing as 'so big which impossible to fly', yet the boeing engineers worked day & night to make it a reality...
The Boeing 747, commonly called a Jumbo Jet, is one of the most recognizable of all jet airliners and is the largest airliner currently in service. First flown commercially in 1970, it held the size record for more than 35 years until surpassed by the Airbus A380 (due to enter service in early 2007). The Soviet-built Antonov An-225 cargo transport remains the world's largest aircraft in service, while the Spruce Goose had a larger wing-span.[2]
The four-engine 747, produced by Boeing's Commercial Airplane division, uses a two-deck configuration. A typical three-class layout accommodates 416 passengers, while a two-class layout accommodates a maximum of 524 passengers. The hump created by the upper deck has made the 747 a highly recognizable icon of air travel. By February 2006, a total of 1430 aircraft have been built or ordered in various 747 configurations, making it a very profitable product for Boeing. [3]
The 747-400, the only series currently in production, flies at high-subsonic speeds of mach 0.85 (567 mph or 913 km/h), and features intercontinental range (7260 nm (13446 km)).[4] In some configurations this is sufficient to fly non-stop from New York to Hong Kong — a third of the way around the globe. In 1989, a Qantas 747-400 flew non-stop from London to Sydney, a distance of 11185 miles (18001 kilometres) in 20 hours and 9 minutes, although this was a delivery flight with no passengers or freight aboard.[5]

I believe the first 747 was flown in 1968 or 1970. There were lots of large jets before the 747 like the B52 in the 1950s or the British Comet in the early '60s (crashed often), but the 747 was the jet that really coined the "jumbo" name.

I think it was just after they shipped all the dinosaurs off to uranis.
I've heard of dumbus americanus but this is the first time I've
found a dumbus australianus.
