My ideal SAR machine would be the upgraded version of the S92.(Offered for the U.S. President I think.) For all bases!! As for the A139 being proven, well I think you should have a look at the other thread on this topic. But please don't turn that into another p-----g contest!
Do you only have one winch? Well, your Sea King is not as superior to the clapped out old Bristow sticky bun as you thought then! Dual hoist, similar capabilities for about seven or eight years now! I thought the Norwegian Sea Kings had been fitted with a dual hoist several years ago as well. Again, not a dig. Different priorities, different routes.
