I am seeking any information on Michael Greentree, a RAAF Officer I served with at RAAF Richmond in 1974 - 1975 while I was an USAF Exchange Officer with 36 sqn. Mike was in 37 Sqn and I last heard that he was living in the Adelaide area. He probably retired in 1988 - 1993 as a Wing Commander or Group Captain. Any assistance will be greatly appreciated.
