Crab, I'm intrigued on two counts:
Firstly, regarding the non-applicability of TUPE: surely, as long as their current employer was prepared to release them - possible sticking point there - mil SAR personnel that the contractor thinks would be an asset would be snapped up in the recruitment process anyway?
Secondly, why on earth would higher hover heights necessitate "ever more reliance on the Hover Trim" in, for example, an S-92? Just curious.
