John was named by his parents after Mercury 7 astronaut John Glenn.

He was educated at Harvard and decided to follow in his father's footsteps of becoming an astronaut, before joining International Rescue.

As space monitor aboard Thunderbird 5, John has the most important task of relaying received calls for help back down to IR headquarters at Tracy Island, on Earth. As IR's "gatekeeper," he can expect to hear just about anything - from lost boys, to secret agents, and even (wait for it) giant alligators!

John is also very fond of astronomy, and has had several textbooks that he's written and published. With the aid of TB 5's state-of-the-art telescope, he actively observes and photographs the heavens...and his incessant space-searching led to the discovery of the Tracy quasar system.
