Dilbert Groundloop is a comic character conceived by Capt. Austin K. Doyle, USN and Lt. Cdr. Robert Osborn, USNR shortly after the Attack on Pearl Harbor during World War II.[1][2]
An early aviator, he was used in training manuals, like Taxi Sense, and training posters for the United States Navy.[3] Dilbert was specifically shown doing things that pilots shouldn't do with the terrible and comedic consequences of his actions illustrated for the benefit of future pilots.[4]
The Dilbert training materials received wide recognition by Navy personnel and others, due to Osborn's distinctive linear style.[5]
