The beginning of flight testing accompanied a key milestone known as Type Inspection Authorization, which shows that aspects of the design are ready for government evaluations, The Air Current reported earlier, citing two unidentified people familiar with the program’s progress.
The 777-9 is the longest version of the wide-body 777X.
