Thanks everyone for the comments. I'm still not 100% convinced. It's the aircraft on the taxiway at the bottom of the picture that has me bothered. Maybe if Groundbum could tell me how to establish the date and time of the images it would help.
One thing puzzles me. I remember the original aerial photo survey that took place in the UK during the '80's. An aircraft flew a grid pattern at a constant altitude across the UK and established the first photo 'map'. Diaz and Groundloop mentioned current aerial photography. Is this still an on-going project and if so, who is funding it?
I, like HD, always believed that the Google Earth maps were generated by satellite imagery. The detail provided is not that bad. I already mentioned the detail that is visible of my home in Thailand where, I know, no aerial photo mapping has ever taken place.
