Crab - 27 accidents all with the same common theme!! Failure of the "human" to manage the flight path. There are military, military in civil role and of course full blown civvies all making these mistakes. No one appears exempt from these insidious mistakes.
The singular problem with categorising them as "Pilot Error" is that we fail to identify, assess and correct the environmental issues that lead to these errors.
One incident, where an S76 hit the sea then took off again was put down to the handling pilot having a tough session in the gym!!
Forget pilot error. That is just the bit at the end that all of us seem susceptible given the specific circumstances. If we are to make a serious effort to stop these events we need a more discerning approach to the problem.
CAA know tis and so do most of us at the pointy end of flight safety.
