High Altitude Bombers 1941.
R.A.F Boeing Fortress 1 from Number 90 squadron.
In the summer of 1941 Boeing Fortress I heavy bombers of No.90 Bomber squadron,Bomber Command,carried out daylight raids in the sub-stratosphere over France & Germany,these aircraft flew from a base in East Anglia,these aircraft were specially camouflaged in a particular pattern and are of special note,the upper surfaces were camouflaged in dark green & dark earth,however the lower surfaces were painted in a bright azure blue,note that no national markings were carried below the wings.
The Fortresses were later transferred to Coastal command where the azure blue was overpainted in white.
Authors note: The dark earth colour on the illustration above has faded on my original artwork due to degradation of colour pigment to give it a mauve tinge,disregard this and use standard dark earth for your models.
