I am not yet sure that this is something that should be taken at face value. Some other format may yet replace it.
What should be clear is that the world has changed since 2004. The 61s have gone and Sea Kings are due to go at Lossiemouth and Sola. Fast and well-equipped SAR aircraft are at Sumburgh and soon at Inverness and Sola.
Lots of S92 and EC225 have entered crew change service.
