Most operators seem to be working towards using NVGs, but the FAA is a severe holdup. Their extremely slow approval rate is the problem. My company has the goggles on the shelf, but the FAA will only approve bases at about the rate of one a week, and that's only because the company is pushing them. It will take well into next year to get the NVG approval for all the bases, even though the equipment is on hand, and the installation is as standard as it can get. The FAA fought all NVG use by civilian programs for years, and only started allowing them very recently. NVG use will become pretty much universal, I think, but it will take time.
I also think SASless is well behind the times. FAA inspectors visit one of our bases pretty much every day. Enforcement has been a priority for some time, and the only holdup on that has been the lack of personnel, left over from the previous administration which didn't want to enforce any regulations on any company at any time. It's getting better, but slowly.
