Helicopters are expensive to operate and even more expensive to operate safely.
As long as bean counters are controlling helicopter operations they will try to save money, whether it be on servicing or training or equipment levels etc.
Unless the appropriate rules and regulatory body are there to prevent safety being compromised in the pursuit of profit margins, we will continue to crash helicopters in the same old ways.
Where a conflict of interests occurs - eg the aforementioned presence of Shell as both part of the safety regulators and as an operator out to make profit - it is no wonder that mixed messages are sent.
