Rigga - re. the weather vane, Norfolk coast indeed. Initially it had main rotor blades but the blade cuffs weren't man enough for North Sea gales ! ... the 'Jesus Nut', on the other hand has remained intact !.
Herod - I think we have previously mentioned co-location at Tern Hill. I was with CFS (H) from 66 to 71 (66 to 68/9 at Valley.)
Shytorque - 'computer out' with the Whirly was always ;interesting. We had a Master Pilot come to us, who had previously done a tour on the piston version. Initially, his hovering was 'variable' ... until he went 'computer out' ! He reckoned he had problems adjusting to the 'scan' without having to constantly reference the rrpm.
