unflyable
Too damaged airborne
Unflyable describes an aircraft that cannot be safely or legally operated, whether due to mechanical failure, weather conditions, or design flaws: The plane was grounded as unflyable until repairs were complete.
The term also applies to airspace or routes deemed too dangerous to navigate: Fog made the corridor unflyable.
