The mission was something of a failure. There were 19 of the 63 planes carrying cameras but only 3 planes took photos. The three planes that took photos (62, 34 and 14 according to the mission report) were in the first and second formations, but 8 other camera planes in those two formations did not take photos. Only 18 planes of the 63 on the mission dropped their bombs. The target co-ordinates, wX425376 (48° 01' 21'' N, 9° 38' 55'' E) is just a farm field today. The mission report reports bombing a wooded dispersal area, so perhaps the actual target was one of the nearby woods either to the south or east. The co-ordinate translator used to translate to longitude and latitude is often a little "off".
