Thunderbird 1

Thunderbird 1 is a massive hot air balloon launched from the IR Ballooning HQ. It is usually piloted by Sam Saltzman but can also be piloted by Commander Norman, Billy Boxiloxi or Kathleen the cow.

In Oh Dear, Miss Malone, it was used to carry Kenny's deep sea diving equipment to Aristotle's secret lair.

In Meet Me At The Spot, Billy used TB1 to get to save Grandma from the Nursing Home Residents.

It was destroyed in The End, along with TB2 and IR HQ. Kathleen was also killed in the process, much to Mr. Mouseff's dismay.
