Believe me my question is NOT intended in any way to provoke any sort of argument because I am totally ill equipped to have an argument with anyone . But I do wonder sometimes if Rolls Royce make aero engines these days or just assemble them --they seem to buy in bits from all over the world. Does this strain quality control?
When I was a kid the impression was that they made everything -even all nuts and bolts--from alloys they made themselves in their own foundries. They had, it seemed, total control.
Who made the apparently crude oil pipe for them?
