70 Squadron lost two Wellington aircraft in a daylight raid on Valona, Albania on 7 November 1940, both shot down by Fiat CR.42s and Breda 65s.
The aircraft were T2731 (Fl Lt T A Brian) which went down in flames and T2734 (Sgt G N Brooks) which was seen to explode in the air.

Would like to know which aircraft Ellam was on. There are suggestions that it was T2731.
