So that leaves aircraft which don't have the range/capacity to match the Sea King. So much for 'no lesser capability'!
What else will be compromised and fudged as this competition for a contract, which still has to prove itself value for money, pushes on to its rather protracted conclusion?
Whilst the casualty doesn't care what colour helicopter comes to the rescue, they might be concerned that contractual shortcomings and compromises might mean that no-one comes at all because a reduction in capability was accepted at risk.
