This is the rare Hawk Industries GAF-125 GAFHawk 125, seen here on 11 June 2006 in storage at All West Airport near Delta Junction, AK. Only one prototype was built, and registered to Hawk Industries Inc. as N101GH on 9 december 1981. It is currently still registered as such.
The aircraft originally flew with a PT6-45R turbo engine, but this has since been replaced with a somewhat weird-looking radial engine. The company logo of Hawk Industries is still featured on the tail. Oh, and the funny thing on top of the fuselage between the wings is the fuel tank.
