He wasn't in marginal weather when he sent/read texts.
He was above it in clear blue skies.
he placed undue commercial and operational pressure on himself
I don't think it was self-imposed pressure but, whether it was or wasn't, it still raises questions about why he felt the need to do it.
It's not the first time it's happened and it won't be the last unless the industry is prepared to face up to the direct and indirect pressures on corporate/freelancer helicopter pilots and think of some way of doing something about it.
He was a very experienced pilot, and from what I read on the original thread, well respected by his peers but he still felt he had to try to get the job done. Why did he feel that?
Instead of just dismissing it as yet another 'one off' we need to look more deeply into the pressures that cause this sort of thing to happen time and time again in the corporate world and try to do change the culture that leads to it.
The culture sure ain't gonna change on its own.
