Jack (great username by the way !),
These shots are taken from the "southside" of the airfield and from public bridleways, the bridleway runs the entire length of runway 06R/24L so you can plot up anywhere along it, these shots were taken when landings were on 06R - its probably one of the best places for airliner photography in the UK, if you want specific directions drop me a pm.
Regards
Russ.
