USAF rescue.
One online news report puts the rendezvous point as being 320 miles off the Irish Coast. I don't know if this is outside the range of the S-61N or not. Given the initial location of the ship (approx 600 miles out) when the mayday call was first made, the HH-60G probably looked like the best option at the time and it certainly gave some flexibility with its air-to-air refuelling capability. The 2.5 hours over the ship could partially be explained by work being done on the casualty to prepare him for the winching and trip back to hospital.
In any case, well done to all involved. This mission will no doubt go down in the history of the unit involved as one of their greatest rescues.
