On April 9, 1967, the first 737 takes off from Boeing Field. The so-called "Baby Boeing" is designed to fill the gap between optimum 727 and 707 markets, but initial sales are slow in competition with the first Douglas DC-9s. It is, in fact, the first Boeing plane to be launched with orders from a foreign airline (Lufthansa) rather than a domestic carrier. However, the 737 and its many Renton-built variants and descendents will have the last laugh by becoming the world's most successful jet airliner with more than 4,000 orders to date (2001) and new generations still rolling out or on the drawing board.
