FWIW, a brief and not necessarily full account of my financial status during the late 1970 - the Bristow strike was April ‘77.

Interesting times indeed, and BALPA proved worth every penny of my subscription - up to, and including, taking on the successor CHC successfully decades later in an Industrial Tribunal.
Best wishes to the current crews in the present unhappy situation; despite it all it was a great life (just don’t mention Robert Maxwell!)
