A Boeing 777-9 ordered by Singapore Airlines is progressing toward its first flight. According to aviation updates, the aircraft, identified as WH291 and carrying U.S. registration N20092, completed brake and taxi tests last weekend. Its first flight is tentatively scheduled for October 14, subject to testing readiness and operational requirements. No official confirmation of this first-flight schedule has yet been obtained from Boeing or Singapore Airlines.
A photograph taken by aviation photographer Hongming Zheng at Paine Field (PAE) in Washington state on October 10, 2026, records N20092 on the ground. The photo information identifies it as a 777-9, and the photographer notes visible elements of Singapore Airlines' livery and folded wingtips, providing an image record of the aircraft's recent ground activity.
Brake and taxi tests are preflight ground checks used to assess aircraft systems during ground movement, control and deceleration. In the supplied update, October 14 remains a tentative date and must not be treated as confirmation that the aircraft has completed its first flight. The term first flight here refers only to this individual aircraft's maiden flight.
The 777-9 is a large twin-engine widebody aircraft in Boeing's 777X family, featuring GE9X engines and folding wingtips. Boeing's published specifications list a fuselage length of 76.7 meters and an extended wingspan of 71.8 meters, reduced to 64.8 meters with the wingtips folded on the ground. This design balances aerodynamic efficiency with airport ground infrastructure requirements.
An individual production aircraft's first flight does not mean it has been delivered to an airline or is ready for passenger service. In its 2026 update on 777-9 testing, Boeing said production-configured aircraft were supporting certification work alongside dedicated flight-test aircraft, with deliveries expected to begin in 2027 at that time. Further testing, delivery and operational arrangements for WH291 remain subject to official announcements.
