The Boeing 747 was the largest passenger aircraft in the world for over 36 years.
The Boeing 747 is one of the most durable passenger aircraft. Its development started when Pan-Am boss Juan Trippe approached Boeing boss William Allen in the 1960s and asked for a new passenger plane that was twice the size of the Boeing 707. The conversation between the two entrepreneurs, in which Trippe said to Allen: “If you build it, I buy it”, is legendary, after which Allen is said to have replied: “If you buy it, I build it ”(If you buy it, I build it).
In the end, the Boeing 747 was even two and a half times the size of the widely used 707 at the time and was initially even supposed to have an upper deck along the entire length of the plane. However, the idea was rejected after the aircraft could not be evacuated in under the 90 seconds required.
On February 9, 1969, the first 747 took off on its maiden flight, almost five months before the Apollo 11 mission landed on the moon. The 747 remained the largest passenger aircraft in the world until the Airbus A380 in 2005.
