As written Grandma is erroneously stopped from leaving on a flight to Paris to watch Tommy's non-existent French astronaut girlfriend being launched into space. The European Space Agency's Ariane rocket is not launched from Europe, it is launched from South America. The Guiana Space Center near Kourou, Guiana (Guiana is France's largest overseas territory) allows the Ariane booster to lift larger payloads by launching into a near equatorial orbit.
Since Tommy was already convicted and had served 36-months in a Federal prison, he would be released on parole, not probation. He would report to a Parole Agent not a Probation Officer. Parole is an early release program whereas probation is a diversionary program.
Even though the European Space Agency officially has a manned space program it does not have a manned space vehicle to launch it's astronauts into space. The ESA has depended on NASA and the Russian Federal Space Agency to ferry its astronauts to and from the International Space Station.
