 In an altered history of world war two, a test aircraft known as the Triebflugel is about to launch on a new test flight. Based on a real design considered in WW2, the Triebflugel is a three winged, vertical take-off aircraft. Perfect to launch from the middle of Berlin to defend against the increasing Allied assult. Little does the Focke-Wulf crew know however, but the Allies have already heard of their new hope and have dispated their forces.
