Bomber Command Airbases from the air

Last Saturday I flew from Belfast to Düsseldorf. The weather was fine so we could see a great deal such as disused Bomber Command airbases. Perhaps someone can shed some light on which ones they are. The first one appeared right after we had crossed Birmingham (001). The next one (002) came straight after the first. I’m almost certain that the last one (004) is in East Anglia and it is very near the coast.
Any ideas?

Thanks
