They've tracked at least four Boeing 747-400F departed from Munich (MUC), (3x) East Midlands (EMA). Given there's so many teams are based in England - McLaren-Mercedes, Mercedes GP, Force India, Red Bull Racing, AT&T Williams, Lotus (?), Virgin Racing (?)...
and I think some others except BMW Sauber Ferrari, Scuderia Ferrari, Torro Rosso...They might on the Munich flight instead....
