Simon was an air traffic control for a Scottish airport.
Simon eventually worked his way to being an air traffic controller along with Jim, clearing flights for departure and arrival. Jim noticed the Flying Lemur on the tarmac, and Simon radioed in on it, Jim learning the plane's fliers name: Grace Cahill. Simon asked her to squawk her transponder, but as shed flew up, she refused saying she was dropping a package off for a friend. Flying over Loch Ness, Simon and Jim watched as the Ekaterina attacked Grace's plane, and her transponder went dead.
