A German vertical take-off tailsitter interceptor aircraft.
The Focke-Wulf Triebflügel, or Triebflügeljager (Thrust-wing Hunter) was a 1944 German concept vertical take-off and landing tailsitter interceptor designed for local defense of factories where aviation facilities were minimal or completely unavailable. It only reached wind tunnel testing when the Allies reached the production facilities, and no prototype was built.

The aircraft was designed to have three large rotor blades with ramjet engines placed at the end. The blades are placed on a ring around the fuselage, thus functioning like a propeller in horizontal flight. The rotor spin is initiated with rockets until the airflow is sufficient for ramjets to work and the rockets would expire. The aircraft would takeoff vertically in a helicopter-styled manner, and tilted over for horizontal flight. To land, a tricky, perilous maneuver would need to be done: The aircraft slows down, tilts upwards to vertical, then reduce power to slowly descend to the ground. The obscured vision and upwards direction meant the pilot would have need extensive training specified for landing the Triebflügel.
The Triebflügel appeared in Captain America: The First Avenger, used by Red Skull to escape the first factory raided by Captain America.
In Suyukaz's Fiction
Spook doubted the tactical ability of the Triebflügel, admitting he couldn't think of anything that would happen next in the aircraft's development (by saying he wouldn't guess if the craft could take off or not). Lily was astounded with the vertical takeoff design, and imagined how useful it would be for aircraft carriers. Yuki was also impressed but preferred assuming it would never fly past its planned operational range.
