AUS 09-05-0039/AS1. SFC - 2500FT AMSL, 10 MAY 10:10 2009 UNTIL 10 MAY 10:45 2009.
which indicates it's on Sunday 10th at 10.25z (11.25 local time); also, should be 2 passes, but I don't know which direction(s). Should cause a little bit of chaos for Heathrow inbounds and/or outbounds at that time, which is only right and proper!
FYI, there are also similar flypasts at RAF Hendon Museum in the next week or so ...
