In 1965 the Boeing name was synonymous with big, multiengine jet airplanes. So when the company announced its new commercial twinjet, the 737, it quickly earned the nickname “the baby Boeing.” While the future market for a small commercial jet looked to have minor promise at the time, no one expected the Baby Boeing would become the jet-age version of the ubiquitous DC-3. With more than 7,000 orders since then, it’s hard to think of the 737 as anything but a tremendous success.
