If the co pilot dos deliberately crash the aircraft through depression then I feel sorry for him as well as the poor souls behind him. I Witnessed someone with depression and I would describe them as numb and I could realistically see someone descending the aircraft breathing normally almost acting in third person.
With airline management known for being some of the most ruthless out there how many others are running close to breaking point?
Management are disrespectful, constantly looking to cut terms and conditions and placing finacial pressures on new joiners that are incompatible to the post undertaken.
The regulators are indifferent and the politicians won't touch anything until it gives them bad press.
And all the while the foxes are in charge of the turkey farm!
