Hey 72 Cuda,
The old 10th ARS up here in Alaska (the forerunner to my current squadron) flew OA-10’s (the prop jobs so as to not confuse anyone) well into the late 40’s and even early 50’s for SAR. I’ve even got a photo of one on Elmendorf doing a JATO take-off.
The OA-10’s were later replaced by HU/SA-16B albatroses. I’m planning on making a JATO OA-10 in 10th ARS markings. On another note, the JATO was supposedly used to get out of the many short strips, small lakes and for getting of the arctic ice flows and glaciers that they woould land on using only the hull (no wheels or skis). I’ve heard both sides as far as whether they reinforced the hulls or not.
On the O/A-10 Hogs, all I know is that we’ve had both designations for the SANDY role, and I was told that they’re basically the same aircraft.
