According to Wikipedia: List of Donald Duck Characters.
Launchpad McQuack first appeared as Scrooge McDuck‘s pilot in the DuckTales cartoon series. He later appeared in the spin-off series Darkwing Duck as Darkwing’s sidekick. He is usually depicted as brave, good-hearted, and incredibly dim-witted. While a skillful pilot, he is very bad at landing and almost always crashes instead but, to his credit, he and his passengers always survive such crashes, and he takes a strange sort of pride in being able to crash any imaginable aircraft (“If it’s got wings, I can crash it!” he has proudly proclaimed).
Launchpad McQuack is also the fictional name of a song in Scott Pilgrim vs. the World, where this blog got it’s name.
