Ballsout,
Yeah, that puts it more clearly.
I don't think it was 8 ICI bosses being killed. I thought it was 3. Maybe I'm thinking of a different incident?
The service ICI used was variously called the Co jet and/or the McAlpine jet. However, the service used on the flight that I am thinking about was, I thought, an irregular acquisition of a service.
as you say, ICI Shell BP et al then started insisting on 2 pilot flights only.
I seem to remember that the Insurance Cos started to be difficult around that time, aswell. However, i don't think they had any input in to CAA rules.
