We have seen another Helicopter Manufacturer issue such public statements in the past.....and it later turn out they. had a major problem in the design of their aircraft.
How much credence can we put into Leonardo's Statement?
If it is credible and based upon the results of the examination of the wreckage.....then that would point a finger directly at the Crew as the weather was benign.
Has any more information surfaced about their backgrounds, training, medical history of the crew, and their 139 experience been made public?
Anything that would put into question their fitness for that particular flight or climatic conditions (dark, over water, lack of horizon....etc).
