I have a question.
Just because the world and his wife uses a particular brand why is there the automatic assumption that we have to?
When the world was flying Neptunes the RAF had Shackletons.
When the world was flying Orions the RAF had Nimrods.
It never seemed to have an effect on how the RAF inter-operated in joint/coalition ops. Why would operating P-1s against P-8s make a difference?
