Hello/Bonjour,
Alex, I have heard of that change but I think that was not going a problem. Perhaps you already know but I found some interesting documents last evening in that library [Lawrence Layden scrapbook, College of Charleston Libraries, Charleston, SC, USA.]:
http://lcdl.library.cofc.edu/lcdl/?f%5Bcollection_titleInfo_title_facet%5D%5B%5D=Law rence+Layden+Scrapbook%2C+1941-1945 The collection consists of a scrapbook compiled by Lawrence "Ed" Layden, an officer with the 67th Tactical Reconnaissance Group of the U.S. Army Air Corps during World War II.
Steve - thanks for the info - I found this, so, we can already remove January for the missions carried out.
MONDAY, 20 MARCH 1944 - TACTICAL OPERATIONS (Ninth Air Force): 67th Tactical Reconnaissance Group completes a series of 83 missions (begun on 23 February) during which photographs were made of 160 miles (256 km) of French coastline and 2 inshore strips, each 120 miles (192 km) long; 9,500 prints are produced and no aircraft are lost.
Best regards,
Frederic
