I was at the Canadian Warplane Heritage Museum in Hamilton (CYHM) last week and took these pictures.
The S-51 (H-5) was built for the RCAF in 1947 and served until 1959.
I find the hoist /stretcher arrangement ingenious if not scary for the casualty.
The S-51 is not airworthy but the museum has a lot of aircraft that are and fly regularly i.e. the: Lancaster, B-25 Mitchell, Harvard, DC-3, Chipmunk, and Canso.
Its worth a visit if you’re in the neighborhood.
Breaking out on top, I thought the picture would turn out better but.(not)
