I think the blame for the cheap part, if it is true has to lie with the oil/gas company that has contracted HNZ.
If money wasn't an option why did they change from BHL to HNZ, especially if Bristows were so shiny with all the SAR guys to match.
The company's letting the contracts out are the ones driving the prices down so if HNZ can do it cheaper good on them but the customer gets what they pay for.
