Two CFM LEAP-1A engines successfully completed a five-hour, 29-minute flight powering the new Airbus A321neo, paving the way for delivery of the first LEAP engines on the largest member of the A320neo family in 2017.

As TIME magazine’s technology reporter Victor Luckerson compiled candidates for the early January edition highlighting “innovators in science and technology who will help shape the world” in 2016, he remembered the exotic manufacturing underway at GE Aviation.

CFM International’s advanced LEAP-1A engine was today simultaneously awarded Type Certificates by both the European Aviation Safety Agency (EASA) and the U.S. Federal Aviation Administration (FAA).
