The Colonel is a member of the United States Air Force. His real name is unrevealed, but he serves under a similarly unnamed General on a secret military experimental project that produced and tested the XJP Jet Pack. He plays a film showing the testing of the jet pack to the General, but he also has the misfortune of learning it has been lost overseas from an unnamed lieutenant while the General is present. He later gives the order to have it recovered, unaware it has washed up on the island with the castaways of the S.S. Minnow.
- The Colonel was played by actor Edward Falkner.
