The Three-Holer

摘要

To anyone born after 1990, the Boeing 727 is that odd-looking airliner in the far corner of the airport, the one with three jet engines clustered around the tail, one mounted atop the fuselage. What made the once-ubiquitous 727 such a rarity on today's airport ramps was the noise from its engines, but at one time it was the world's fastest-selling airliner. This year we celebrate 50 years since its first flight-on February 9,1963-and first customer delivery (to United Air Lines, in October).
