Boeing’s third 777X, WH033, took to the skies for the first time today, a welcome milestone in the rollout of the aircraft, after its initial delivery schedule was recently pushed back.

Sporting Boeing’s new testing livery, WH003 took off Paine Field in Everett, Washington, at approximately 1:55pm local time on Monday. 

The aircraft headed to Moses Lake, where she performed a few touch-and-goes, before heading back to Boeing Field. 

WH003 touched down again at 4:42pm local time. 

The new milestone for the Chicago-based manufacturer follows in the footsteps of two previous test flights, with WH001 performing its maiden flight on 25 January 2020, and WH002 performing its inaugural flight on 30 April.

According to Boeing, the latest test flight, with WH003, was intended to test its propulsion performance.


WH003 and WH004 – the next in line to perform its first flight – are both expected to be delivered to Lufthansa in 2022, after the delivery schedule of the first 777Xs was pushed back, due to the COVID-19 pandemic.
