So from what you're saying, one of two things could have been happening.
1. The Falklands duty SAR S92 has been manned by trainees
Or 2. The Falklands duty SAR S92 has been manned by fully qualified SAR crews.
My guess would be the latter in which case they have been depleting their UK resources to man a commercial hydrocarbons SAR support contract. Shouldn't those aircrew have been in the UK doing what the UK taxpayer expects them to do, namely train for and man what is widely recognised as an undermanned UK SAR project that is behind on its training?
