Yup remember Bena and Asaloka - Daulo is indeed the road gap I couldn't think of. Bundi Gap was between Kundiawa and Ramu Valley not Goroka and Ramu Valley.
I knew Jasper very well but don't remember 'Jasper's gap' still being called that in the mid 80s onwards - which Gap was it again?
Is Jasper still upright? I don't remember hearing he'd passed but he must be VERY old now - His first flying job was hauling 'freezer' between Goroka and Chimbu in a Tiger Moth on his days off from ATCing in GKA tower. When I first got to know him he'd recently retired from PX/F28 and was back at Talair flying the DHC8.
True Gentleman.
