As a derivative of the already common 747-400, the 747-8 has the economic benefit of similar training and interchangeable parts.Boeing has studied a number of 747 variants that have not gone beyond the concept stage. Several versions of each variant have been produced, and many of the early variants were in production simultaneously. All of the companies solved this problem by moving the cockpit above the cargo area; Douglas had a small "pod" just forward and above the wing, Lockheed used a long "spine" running the length of the aircraft with the wing spar passing through it, while Boeing blended the two, with a longer pod that ran from just behind the nose to just behind the wing.The 747 was conceived while air travel was increasing in the 1960s.In April 1966, Pan Am ordered 25 747-100 aircraft for US$525 million.
