I have just read the report and something doesn't add up:
The report gives a time of 13:16.
A BA A320 landed at 13:13 (G-EUUR) and G-MIDY landed at 13:21.
Lufthansa D-AIPA landed at 13:19. The report says the aircraft was "blue and white" which would seem to indicate a BA aircraft, rather than the Lufthansa. G-MIDY passed the spot indicated on the map at approx 700' at 13:20.
Aircraft in between these times were a mix of B777, an Aeroflot A330 and a SAS B737.
I have seen buzzards around this area on a number of occasions.
