Well done to the Prestwick crew.
Some appreciation should also be given to the Coastguard Officers at Belfast who developed the apparently successful search plan that placed the UK Coastguard SAR helicopter into an area in which the Mk I eyeball became effective.
Given the number of known unknowns and the possibility of an unknown unknown, the Coastguard Officers at Belfast, or whoever was search planning for them, deserve a pat on the back. They were either highly competent or blessed with good fortune - possibly both. Good result in any case.
Look forward to hearing the survivor's story.
