Can remind you the school case of the Concorde ..
Only one crashed .. and the entire fleet was grounded.
Explain me this with statistics
There were only around 12 of them flying for only 2 airlines worldwide. The
cause of the accident was rapidly established and a rectification programme was formulated. One of the two airlines did not wish to ground its fleet. The manufacturer was looking for a reason to withdraw from the expensive investment needed to keep this tiny and specialized fleet flying. Economically the aircraft had been badly affected by the reduction of premium class air travel post 2001. The political will had evaporated to simply postpone the inevitable.
