Bell OH-58A 68-16830 was upgraded to an OH-58C. With a more powerful engine, the early OH-58Cs also had flat windscreen panels. It was to reduce reflections on the battlefield that may give away it's position, the flat panels were found it restricted forward vision compared to the standard curved windscreen. This aircraft is on the US civil aviation registry as N76KP to Northwest Helicopters but is displayed unmarked.

Originally 70-15708 with the US Army, this Iroquois was added to the US Forest Service in 2011.

The Soloy Pathfinder 21 was a conversion of a Cessna 208B powered by the Soloy Dual Pac (two side-by-side P & W PT-6 engines driving a single propeller) developed with Pratt & Whitney Canada. A 72 inch fuselage extension aft of the wing and extra capacity for cargo or baggage under the fuselage were other modifications. Soloy abandoned the program when the FAA required it be certified under FAR 25 (Transport category) requiring higher airframe strength that would be too expensive if not impossible to implement.
