I know John Pym well when he came to Oz to work for a short time in the CAA before going off to fly for Royal Brunei (B747) and now in Hong Kong with Cathay.
He has told me stories over a few sherbets about his time with the Omanis on Jags.
Wouldn't be at all surprised if it was him.
If you read this John - all thebest from the Canberra gang.
