I cannot recall Bristows not having spare crew prepared to help out
Things have obviously changed for the worse, given that Stornoway went off state for 24 hours earlier this summer due to "pilot sickness". No military flight has ever gone off state for so long for a single member of the crew. What a wonderful model to adopt in a few years' time.
At least the AW139s are doing fine. Apart from Portland being off state TFN with "technical issues" last time I looked...
