Also just to clarify for anybody else joining the discussion on page 2,the youtube video I posted on the previous page had been captioned incorrectly by the youtube channel uploader,Eisenhower's P51 flight was 4th July 1944 and was to reconnoitre the St Lo area in preparation for the break out from St Lo - nothing to do with the 'Bulge' which was months later in winter.
Always best to cross check any info gleaned from TV/youtube/internet
