In my opinion Managed Transition was primarily devised as a tool for MOD manning to maintain SAR cover during the handover phase. An added benefit is that it aIlows Bristow to cherry-pick the military element of their crewing solution. The notion that only current crews should be eligible is nonsense; of course it makes sense for a large chunk of crews to be in current practice but it doesn't take an awful lot of effort to get those (of appropriate skill and attitude) who are non-current up and running again. Despite the belief of some, SAR is neither a black art nor a discipline that those who have had some time elsewhere are unable to return to successfully.
