Absolutely beautiful shots Luthier! The Spitfire comming in low and fast under the He 111 nose looks frightening! If these are peaceful skies, I fear what warlike skies will look like
A small comment on British markings (again, if you will forgive me):
The standard RAF colour for squadron codes in 1940 was "dark sea grey" for Hurricanes and "sky grey" for Spitfires. The dark sea grey colour is markedly darker than the white used in the roundels, as seen in this photo:
This restored Hurricane showing the same colour:
The sky grey too was darker, though not as dark as the sea grey series of colours. The only figther squadron I have found that used white for codes in 1940 was No 261 Squ, operating Hurricanes from Malta.
There were exceptions to the "dark sea gray for Hurries, sky grey for spitties" policy. Here's the exceptions according to Ward, Cooksley and Shores, Aircam Aviation Series No S1, battle of Britain:
Hurricane squadrons:
* No 56 Squ: Sky grey
* No 111 Squ: Medium sea grey
* No 145 Squ: Sky grey
* No I51 Squ: Medium sea grey
* No 242 Squ: Sky grey
* No 257 Squ: Sky grey
All other Hurricane squadrons used dark sea grey
Spitfire squadrons:
* No 66 Squ: Changed from dark sea grey to sky grey in late september
* No 72 Squ: Dark sea grey
* No 92 Squ: Changed from dark sea grey to sky in october
* No 152 Squ: Dark sea grey
* No 609 Squ: Dark sea grey
All other Spitfire squadrons with sky grey codes.
