Millennium Shortcut

The Millennium Shortcut is a helicopter plane that was invented by Gyro Gearloose in the DuckTales special "Time is Money". The plane is piloted by Launchpad McQuack and Bubba the CaveDuck when he initially was going back to his time period until he decided to go back and stay with Scrooge. The helicopter can travel through time and runs on bombastium, which was something that Gyro also came up with.
