Boeing's newest aircraft, the 737 Max, was on display to the public for the first time this week at the Farnborough Airshow as the U.S. aerospace giant approaches its hundredth birthday, with orders remaining strong.
The 737 family is Boeing's most successful aircraft range and the latest Max model - which is due to be delivered in 2017 with launch customer Southwest Airlines - was borne out the desire for airlines to have more fuel efficient planes.
"It goes back to when we launched the program because...all of our product development work is really done with the customers. And at the time what they said is they really like the 737, it's a proven performer, but what we really want is more fuel efficiency," Keith Leverkuhn, vice president and general manager of Boeing's 737 Max project, told CNBC in an interview earlier this week.
"So we set about to try and create an iteration that brought in all the available technologies that would allow us to improve the fuel efficiency as well as the emissions and the noise."
