"It was unflyable
-- literally -- without a digital flight computer on board, which made corrections to the flight path 40 times a second," said Christian Gelzer, chief historian at the NASA Armstrong Flight Research Center in southern California (where the plane was tested) in a phone interview.
He said that when engines are operating at a low percentage, the helicopter was effectively "unflyable
For example, be ready to depart a day early to avoid potentially unflyable
Iran's entire air fleet totals 298 planes, so 42 percent of them are grounded and unflyable

On the second pass he hit a 50-foot tower 40 feet up, making the airplane unflyable
and killing all aboard.
Realizing the importance of using instruments to fly in adverse weather, the Air Corps purchased six of Link's trainers after he demonstrated their effectiveness by flying to a meeting with Army officials despite foggy conditions the military had deemed "unflyable

They would have to put anti-radar coatings one or two meters thick on the planes' wings, turning them into unflyable
Each year we review non-fatal accident reports for which the NTSB has assigned "probable cause." Today we spotlight the unflyable
antics of 2008, an election year during which, among other non-aviation silliness, the Dow dropped over 400 points in one day.
The essential information that arose during these tests was the feasibility of the design, answering several fundamental questions: would the wings remain attached at high speed and high angle of attack; would the aircraft stall at low speed and high angle of attack; what are the impacts of adding externally mounted items to the aircraft; what would happen to the aircraft once an externally mounted device was dropped (would it become unstable, thus unflyable
); and what are the impacts on the aircraft center of gravity?
Kieran Daly of Air Transport Intelligence told Al Jazeera the crash had "a devastating impact to the ground, which suggests that either the aircraft was completely out of control and unflyable
