P2-ART, I have a name listed as Graham Weir (unsure of correct spelling)
Spelling is correct and he owned ART.
He was a Qantas cadet who got told to go occupy himself for a year or 2 when QF had a surplus of cadets. He joined ATC and was in Hagen with me in the mid 70's. ART crashed whilst being ferried south.
Last I heard he was check and training with QF.
He also teamed up with Tony Karras and flew choppers in PNG for a while.... and pranged (ground looped) P2-BOX in Hagen.
