Heard it all on 121.500 too. Sounded to me like they had dozed off - the fighter called them repeatedly for a good 10min before he eventually got an answer, all the while flying formation off their right wing. When they did answer, the (American-sounding) crew didn't sound too proud... But the
Mirage (or
Rafale) pilot was 100% professional throughout. Apparently, Brest ATC could not contact the Gulfstream, so the QRA must have been scrambled from nearby Lorient. According to the interceptor pilot, N223GA was heading North at FL400 at this point.
Cheers
