If the black box flight recorder is never damaged during a plane crash, why not the whole airplane made out of that stuff?
The SR-71 was made mostly out of Titanium (very high strength to weight ratio) and it got off the ground fine.
In addition, a two-seat airplane cost $33 million in 1960.
So, no one would ever be able to afford an airliner made out of it.
