Well in my short time with Bristow, (sixties), if, as a pilot, you were not working and an engine change, for example, was required, you could expect to be out there helping! (strictly in a labouring capacity, of course!). We lived an identical life style, same accommodation, same leave patterns and of course we knew what shifts they worked, as they, the engineers, would know our average flying hours etc. There was no divide.
The trouble with asking a general question about working at Bristow is youre bound to get some diddle head pilot
You did rather invite SASless's sarcasm Tuk Tuk!
