These simplified plane models can be made – depending on the scaling – from different materials width. When assembled and glued they are pretty sturdy toys. In this case beech plywood with a thickness of 6 mm is the proper material.
The drawings are based on profiles that can be found at Wikipedia in vector format. With the simplification details are lost, but the prominent features are preserved.
Starting in 1981 the Space Shuttle did 135 flights carrying up to 24.5 tons of material to Low Earth Orbit. It's save to say the Shuttle was the work horse of the NASA. All orbiters were named after famous sailing ships, including the Enterprise.
The SR-71, called Blackbird, is the fastest plane (non rocket-powered) on earth. Although none of the 32 planes build had enemy contact, 12 of them where lost.
The P-80 was basically the first jet fighter from the USAAF.
The Warthog is sort of a flying machine gun. Nonetheless the construction with 2 jet engines over the wings and the split tail unit give this plane a unique and interesting look.
The Messerschmitt Me-262 was the first plane with jet-engine to be build in series. It was the fastest plane at the time.
The Junkers Ju-52, also called "Tante Ju" or "Iron Annie" was first build in the early 1930s. The corrugated duralumin metal skin and the three radial engines are the main features. There are still some planes out there flying.
The Do-26 is a boatplane build before the WWII. It's sometimes called the "most beautiful flying-boat ever built". Surprisingly it is propelled by diesel engines.
The Waco UPF-7 is the most classic biplane you can image. Build around 600 times this beauty still shows up on various airshows.
Developed in the 1930s, this beauty was able to fly over 450 km/h (280 mph) powered by a 700 hp nine-cylinder, air-cooled, radial engine. So essentially the Z40 was a big fat engine with little wings. That makes it looks like a comic version of a plane and it was probably pretty tricky to fly.
