May I ask if this photo and all others taken in Egypt are out of focus or if some kind of failure with the scanning has occured? They are all very interesting, but this lack of clarity makes any detailed ID very hard. Stig

Stig Jarlevik The originals are out of focus, it might have been due to poor quality of copying several years ago...

SDASM Archives What a pity! Especially those DH-86 shots are very rare indeed, at least to me. Stig

Another "odd" photo. The digit 5 indicates some kind of training unit but none is officially known for this aircraft. Taken to Africa onboard the vessel S/S Empire Liberty (19 Sep 1942) via Takoradi, Ghana (9 Nov 1942) assigned to 601 Sq in the desert and struck off charge 5 Jan 1943. This leaves a very narrow time frame for this aircraft to be with anything else than the 601st. Looking at some other ER27x aircraft, none really fits the bill either. I would welcome further input on this one. Stig

Excellent !

The elliptic wing planform...actually a "double ellipse" was designed to minimise induced (lift dependent) drag; the skewing of the ellipse was to get the local wing centre of pressure onto the unswept main spar ... this being a good thing for the structural design. This was based on the work of the German aerodynamicist Ludwig Prandtl whose work was published in 1934 just in time to contrbute to the Spitfire....nice case of international collaboration eh?

Congrats on Explore!

magnific....well done

remarkable!
