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, All Movie Guide
