Actually Stornoway, Sumburgh and Lee all have standby aircraft. The only base that doesn't is Portland.
Poor old CRAB is trying once again to start an argument and who can blame him. He doesn't have long to slag off civvy SAR before the new aircraft and contractor start with new equipment, proceedures and full SAR standby aircraft - all of which were effectively chosen by the RAF. So apart from a radar that points behind him all his other arguments are lost!
Never mind.... I'm sure he'll think of something else!
