The Boeing 777X program has just hit a major milestone. After nearly five years, a brand new Boeing 777-9 has made its maiden flight at Paine Field Airport. This is the fifth Boeing 777-9 aircraft test aircraft, and Boeing has been preparing it for this occasion since July. Furthermore, Boeing is advancing further towards the plane's certification, with entry-into-service (EIS) targeted for 2026.

The Boeing 777X is the latest iteration of the iconic Boeing 777. Initially launched in 2013, the 777-9 variant was expected to enter service in 2020, but certification issues and technical challenges have delayed the 777-9's EIS by six years. The 777-8 variant, meanwhile, is currently on hold , while the 777-8F will enter service in 2028.
