my father flew the north sea from 1967 till 1983 and he certainly
saw some changes. at the start they did 2 flights per week!
to rigs opening up the forties field etc... all flown in shirt and tie
with a cap covered in scrambled egg. this was BEA helicopters later to become BA and then BIH.
The bird at the time was the S61N, and did a fine job by all accounts. MY father laterly flew the CHINOOK but by this time multiple flights per day and crap crew rotas were in place, along with ever increasing competition from other companys. British caledonian even had helis in the n.sea for a while.
my father is in his 70,s now and says he never misses it, he retired aged 47 so the north sea certainly helped his retirement fund.
