The media isn't scaremongering, the NS rotary fleet are doing a good job all by themselves.
Last trip to NS platform from my son:
Trip out cancelled - a/c unserviceable.
5 hours later landed with replacement
Return cancelled 48 hours (always a really welcome announcement - not), aircraft developed in-flight fault diverted to another rig.
Eventual return flight my son, notices line of clear oil running down from cabin ceiling to floor. Radios pilot. Decision (probably only one available) 'let's keep going, too far to turn back'
I'm sure I don't need to confirm the make of helicopters involved...
Sorry, but if this was say, the London to Aberdeen commercial flight schedule statistics for 4 years, there would be outrage.
