Identify by airplane characteristics

The Bearcat is essentially a shortened F6F Hellcat with a bubble canopy as standard and a taller curved vertical stabiliser. Un­like the Hellcat it has an inward retracting main landing gear.

The F9F Cougar is the swept wing version of the F9F Panther. Like the Panther it has triangular air intakes in the wing roots and a cruciform tail. The vertical stabiliser is also triangular, sort of, with a rounded top. Additio­nally, the aircraft has one engine with an exhaust under the tail.

Few biplanes have a retractable gear and that makes this Grumman family of fighters easily recognisable. The main gear is retracted in the side of the front fuselage, in front of the lower wings, a Grumman characteristic, although the Curtiss BF2C has a similar gear. For the rest these fighters have a stubby or fat appearance thanks to the radial engine in the nose and short fuselage.

The Gulfstream I turboprop was the first large large specifically designed for the corporate market, looking somewhat like a scaled-down HS748. The shape of the engines nacelles is very much the same. It also marked the first appearance of the signature windows still being used on todays Gulfstream jets.

The Grumman Goose was the first of a family of amphibian aircraft. It is normally powered by two radial engines, but modifications exist. The four cockpit windows of the G.21 are flat, so they one of the best ways to recognise it if the engines make you doubt.

A big centre float under the fuselage is a key feature of the Grumman Duck, together with the big radial piston engine in the nose. The main gear is retracted in the side of this large float, and the tail wheel in the rear of it. Smaller stabilising floats are under the lower wings. The upper wings are placed ahead of the lower wings. 

The tall vertical stabiliser with rounded top and the big rounded nose with four flat cockpit windows are the key features of this amphibian aircraft. Its cabin windows are wide, with curved left and right sides.

There is just one aircraft with such a non-circular pancake shaped radar on top of the fuselage. The E-1 is based on the S-2 Tracker, with which it shares many features like fuselage, wings, engines and gear. The tail is different however: the Tracer has an H-tail as a single fin would not provide sufficient stability.

The Tracker maritime patrol aircraft has quite characteristic cockpit windows, with flat front windows and the spherical side windows. The horizontal stabilisers have a significant dihedral. The single wheel main landing gear retracts in long engine nacelles, which end flat.
