Bachstelge the rotary-wing kite which was towed by U-boats to give their observers greater height" rotors are made of wood (ribs and skin) to lower the radar profile and because of shortages of lightweight metals.
Winged missle in front of V1 -
Henschel HS-293 - the worlds first radio controled glider bomb - launched from aircraft and guided visually. Used mainly against shipping it was responsible for sinking the Italian Battleship
Roma when the Italian fleet surrendered to the Allies in September 1943.
Missle against the wall -
Rheintochter - two-stage anti-aircraft rocket, some were radio-controlled from ground based RADAR - two models Mark I at 20 feet in length and the Mark II 17 feet - quite effective but only 80 of the Mark Is were ever launched.
Incomplete missle -
Appears to be another glider bomb the
Schmetterling. Some 60 were produced but never used. Like the HS-293 it had strap-on rocket boosters (4) to aid in launching. The pod on the bottom of the HS-293 I believe is the booster.
The flying wing is probably one of the many glider prototypes built by Horten to work out control problems. Jet powered versions were designed. Most of the construction was of wood.

From Brian Ford's book (Regarding the researchs project of Draegerwerk company in Lubeck): ...the air purification apparatus they evolved for submarine use. It was designed to draw air from a midget submarine through a mixture known as "Kalkpatrone" (soda-lime) and then, after the addition of extra oxygen from a cylinder of the gas, the mixture was returned through a rubber pipe to the occupants. If the 'pilot' of such a midget submarine wished to conserve oxygen, it was possible for him to plug a mask-hose on an adapter on the outlet tube and then breathe it through the special injector apparatus and the soda-lime container, thus taking only the oxygen needed for his personal requirements. He breathed out through the mask, which contained a one-way valve letting the waste gases straight out into the compartment. Thus, though oxygen economies were effected, carbon dioxide accumulated in the atmosphere - although it was naturally, removed by passage over the soda-lime from the air he was about to inhale. This was not a good principle, and in later models of this type it was found to be preferable to allow the exhaled gasses to be passed throught the soda-lime before returning to the compartment. In this manner the carbon dioxide levels were kept low.
