Boeing recently reached the significant milestone of 6,000 Boeing 737s deliveries, a massive achivement by any standards. But does it get the recognition it deserves? It may not be the sexiest aircraft, but the numbers, the longevity, and the usability say it all. To me it was one of the main reasons for the growth of commercial aviation in the 70s, and with 2,000 more on order, it doesn't show signs of stopping yet, even though our recent 100 Greatest survey, it didn't get in the top 5 civil aircraft?
