Early on someone mentioned the DHC series. I was introduced to the C-7A Caribou in Viet Nam. Rugged, indestructable and will almost land in a mud puddle! For FSX I have the DHC-5 Buffalo. Perfect for transporting cargo into remote areas with short or NO runways. If you need tons of cargo space try the C-17. I have snagged it off 5-6000 foot runways with near max weight in fuel and cargo. For me this is my favorite form of "pleasure flying!"
