Dougie,
yes my log book does say Airlift Rodeo, the earlier one I did is recorded as Volant Rodeo. If that famous MSP drop was on May 7 1967, captain Graham F, then I was doing the airdrop check of your loadmaster on that trip.
As I recall there was constant goal post changing mainly to stop one of their reserve squadron teams beating the regulars. I think USAF careers were made and unmade in this competition !
