Pad39a, yes BDI was written off after a ditching off donegal, fuel error on tank selection by the pilot of the time apparently, sometime shortly after the papal visit in 1979. The other yellow bolkow I assume was EI-AWB which was later painted green and white and eventually orange. It returned to Scotland to bristow whom it had been leased from for some six years and itself ditched 5 miles off skegness when it was flying in snow, from that point on an amendment was made that they fly using continuous ingnition to stop engine flame outs in hail Back in the UK AWB again had become G-AZOM.
Alouette 2 EI-AUI eventually returned to the UK as G-FILM and hit powerlines in a far away country flying down a valley with fatalities. BFH crashed in Nigeria somewhere, again with some fatalities. BAM is I believe in Canada, BHO is flying for the UK coastguard as BPWP, and BLY is somehwhere in Canada flying.
