The Boeing 787-10 Dreamliner took off for the first time in South Carolina on March 31.

This plane is the newest and largest model in the 787 family. According to a media release, the four hour and 58 minute flight was a success.

“The 787-10’s first flight moves us one step closer to giving our customers the most efficient airplane in its class,” said Boeing Commercial Airplanes President & CEO Kevin McAllister in the release. “The airplane will give carriers added flexibility in growing their network routes and build on the overwhelming success of the 787 Dreamliner family.”

Tests on flight controls, systems and handling qualities were performed on the flight. Now the 787-10 will undergo more flight testing before deliveries to customers begin in the beginning of 2018.
