Double Standards?
OMR,
If one has worked in the oil patch for at least a day.....the concept of a double standard is a laugh! What multiple of double standards do you wish to count?
The very same "standard" that insists upon twins, IFR and all sorts of other "standards"....happily jump into single engine helicopters elsewhere in the world.
The one thing that is standard is the variation in standards.
The GOM is not the North Sea....and never will be. There is good and bad in that situation but the standards will never be the same between the two places.
