Bertie B, me and MC doing some RUC VCP's in the yellows. Land on with BB' feet up in the LHS, climb away, they think the RHS is the only seat occupied. Mark has tied green comms cord to the yaw (rudder to me now) pedals and proceeds to 'fly the a/c with them, talking to me on the i/c. I then unstrap, and climb down whilst BB flies the a/c unseen from below, minus the ASE yaw channel. Mark makes a grand job of flying the cling on, then hands control to one of the coppers whilst I go down the back and disappear behind the curtain in the radio bay..the RUC chap is a reluctant pilot and his colleagues aren't too happy with his attempts...we landed in a field and they disembarked rather rapidly....
