Boeing 747

When the Boeing 747 entered service in 1970 it was by far the largest, heaviest, most powerful airliner the world had ever seen. With a tail as high as a six-storey building and a wing wide enough to park more than 40 family cars on, it could carry three times as many passengers as the Boeing 707, which was then still the market leader in jet air travel.
Gambling on the success of such a massive passenger aircraft was an enormous financial risk for Boeing and its launch customer. Pan American. Many airline experts believed that the future lay with supersonic passenger jets,
which would soon make the 747 obsolete. Boeing hedged its bets by designing the aircraft so that it would work equally well as a freight carrier, should passenger traffic failed to materialize.
But, as we all now know, the gamble paid off handsomely. The 747 carried forward the revolution hegun by the 707, slashing seal prices to bring long-distance flight within the reach of millions. The age of mass air travel had arrived.
A further huge stride came with the introduction of the 747-400, firsl flown in 1988. A major redesign with upgraded
engines, this variant had the range to fly popular long-haul routes, non-stop. In the first decade of the 21st century, the 747-400 remained in service with airlines worldwide.
