I watched the programme in Hertfordshire and was very moved by it. The family who got stranded in their motor boat with an engine failure gave the other example. I know this talks about things that go on water (how perverted is that?) but it was the same prog.
They made their radio call early, even on the recording on TV you could hear it all clearly (if it was the original tapes!) but when the RNLI offshore boat got there, they had all got their life jackets on and had given accurate location data.
At the end of the prog, they advised that signs were being put on the beach near the camp ground where the family had been staying.
The S61 looked great and it would have been fine if we could have had closer views of the pilot making, as he was adjusting the 'one foot left' and the 'two foot right' as requested, whilst in the hover. Serious rotoring going on!
