The Boeing 737 MAX 8 took to the skies for the first time earlier.

The 737 MAX program achieved the milestone on schedule which begins a comprehensive flight-test program leading to certification and delivery.

With the latest technology LEAP-1B engines from CFM International and Boeing-designed Advanced Technology winglets, the first member of the efficient 737 MAX family completed a two-hour, 47-minute flight, taking off from Renton Field in Renton, Washington at 09:46 local time and landing at 12:33 at Seattle’s Boeing Field.

“Today’s first flight of the 737 MAX carries us across the threshold of a new century of innovation – one driven by the same passion and ingenuity that have made this company great for 100 years,” said Boeing Commercial Airplanes president Ray Conner.

“We are tremendously proud to begin testing an airplane that will deliver unprecedented fuel efficiency in the single-aisle market for our customers.”

During the flight, 737 MAX chief pilot Ed Wilson and Boeing chief test pilot Craig Bomben departed to the north, reaching a maximum altitude of 25,000 feet and airspeed of 250 knots, or about 288 miles per hour typical of a first flight sequence.

“The flight was a success,” said Wilson.

“The 737 MAX just felt right in flight giving us complete confidence that this airplane will meet our customers’ expectations.”

With the other three members of the 737 MAX 8 flight-test fleet currently in different stages of final assembly, the 737 MAX remains on track for first delivery to Southwest Airlines in the third quarter of 2017.
