As part of his never-ending efforts to avoid the German ground troops during WWI, Captain Edmund Blackadder (Rowan Atkinson) signs up with the Royal Air Corps. Crashing behind enemy lines, Edmund is captured by the enemy, forcing Baldrick (Tony Robinson) and Lord Flashheart (Rik Mayall) to race to his rescue -- if only they can outmaneuver Baron Von Richtoven (Adrian Edmondson). "Plan D: Private Plane" made its British broadcast debut on October 19, 1989. ~ Hal Erickson, Rovi
