't Hovis...
.... and
There was no such thing as a helicopter IR - just an Interim Helicopter Certificate. That would go to the blessed few as it cost too much. 99% of our activity was VFR anyway and the VFR minims were often lower than the IFR minims 'cos we flew around at 200 feet, including the infamous ADN Low Level Route.
We were in shirt-sleeves up the front and the pax had the 'new' immersion suits. On really bad days we would put on our UVIC jackets which were a bold - if largely ineffective - step in the right direction.
We - crew and pax - were all wearing 'once only' life-jackets tied around the waist.
Happy days.
