Thanks CP.
I did some more googling and found some pictures of the old girl doing some meat bombing, a spectacular sight!
What is the likelihood that Earl Cherry's aircraft would be operating into Tarin Kowt? I would be very surprised after considering the above information! Are there any other known Hercs (excluding the D model for polar ops) that may be fitted with 3 blades for any reason? This has got me very intrigued!
