The 747-100

Pan Am President Juan Trippe, one of the great pioneers of commercial aviation, encouraged Boeing to build a bigger aircraft. The first flight was in 1969 and Pan Am's first commercial flight took place on Jan. 21, 1970, on a New York-London route. By July 16, 1970, the worldwide 747 fleet had carried 1 million passengers.

In February 1971, the 100th 747 was delivered to another defunct carrier, Braniff Airlines . Later in 1971, the first Boeing 747-200 was delivered to KLM. But in the 1973 oil crisis, the price of a barrel of oil quadrupled to $12 a barrel. This led American ( AMR) and Delta ( DAL) to remove the 747 from their fleets.

The last delivery of the 100 was in 1986 to Japan Air Lines.
