As for why, simple... Logistics missions.
A lot of people questioned what the Huey would do in DCS and then the CTLD script came along and it became a serious contender for a lot of people. I'd say the same opportunities exist for this aircraft. There are a lot of scenarios where logistics support could be implemented in missions, and these guys already have everything they need to develop the aircraft in DCS.
Don't get me wrong, I'd love to see a C-27, C-123, C-130, C-141, AN-12 but this one could be the one to open the doors for other developers to bring their talents to DCS. For everybody who doesn't like them, can you say you wouldn't like escorting one on a multiplayer server or hunting them down to prevent the capture of an airfield?
