Found this website for aviation buffs. Yes, not strictly a PMDG-related topic, but you can track PMDG aircraft such as the 747, 737, etc with this...

Thank you for that. Been using this for ages now to track RW flights of friends from EGLL to New Zealand, vice versa. Was alerted to this when Concorde made its last flight by a radio station caller. Also used it to track the arrival of the Olympic Flame from Athens to its first UK landfall.

Great, thanks for sharing!!
