The Jet-Powered Baggage Buggy was a vehicle invented by Gyro Gearloose in 1952, and wrecked soon thereafter.
One of the last few badly-thought-out inventions of Gyro Gearloose's pre-1952, pre-Little Helper career, the Jet-Powered Baggage Buggy was a vehicle resembling a normal baggage buggy, but which, instead of an engine or a horse, was propelled by crackers attached to the rear wheel. The Baggage Buggy immediately preceded the Think Boxes and was held by all but Gyro himself and Huey, Dewey and Louie Duck to be an embarrassing failure, being noisy, uncomfortable to ride in, and needing the firecrackers to be replaced much too frequently to be of practical use. Gyro abandoned the project in favour of the Think Boxes, using the still brakes-less prototype to get the Boxes to the Black Forest where he wished to test them on random wild animals. He thus wrecked it against a tree when the time came to make it come to a halt. 
Behind the scenesEdit
The Jet-Powered Baggage Buggy appears in the 1952 Carl Barks Ray's A Riot and holds the distinction of being only the second-ever invention of Gyro Gearloose by order of first appearance (though not by in-universe order of creation).
