Just checked IFPS / CFMU.
It would seem to be a ferry flight LGW-BZZ
Monarch A300-600
LGW Kenet SID Baset BZN EGVN
Max 10000 feet
Descent to 4100 feet at Baset
Down to 200 ft at beacon BZN
No reason (published) for it to be
barrelling along at 500 feet, though!!!
Unless they just wanted to and it B]would[/B]
give the military controllers a bit of practice/fun!!
