As proven by the number of times in recent history that the Lossie flight have been tasked into Stornoway's patch to complete rescues that could only be completed by having crews fully qualified to utilise NVGs.
REALLY? From my recollection Lossie were very reluctant to carry out any rescue in recent times. Unless it was relatively good weather, they had a crew to do so or they generally felt like it.
The ARCC cherry picked the taskings for them...
It's amazing that we now have a S92 carrying out taskings that 137 would have and did turn down.
