A "For What It Is Worth" comment.....how does the US Coast Guard or US Air Force crewing, crew duties, and aircraft equipment compare to the RAF SAR/ICG/UK SAR Operations?
The JayHawks and PaveHawks are very similar to the 92's....and the old H-3's/CH-53's would have similarities to the SeaKings and S-61's.
If we did a genuine compare and contrast would we not see some blending of all the various cultures over time as Technology improved, Aircraft design and capability changed, and Operational Experience was gained?
Point being.....isn't there more than one right answer to most questions?
