Europe Trip #19: Aircraft Over London

During my various sightseeing days I managed to photograph a few of the many aircraft flying over London. I'm not sure which airports they were headed in to [I never got my head around where the various airports were in relation to the city!].

Anyway, here they are:

British Airways [Connect], Avro 146, G-BZAY
City Jet, Avro 146, EI-RJS
VLM Airways [???], Fokker 50, OO-VLK
British Airways, Avro 146, G-BZAU
Air France, Avro 146, EI-RJP ???????????? *** Pardon??
[???], MD 900, G-EHMS - rescue helicopter
Lux Air, Embraer EMB-135LR, LX-LGK
Helicopter - unknown ID or details

*** can anyone explain why an aircraft with Air France logos would have an EI- rego? Is this just a leasing thing?
