On the other hand, I used topo maps on the Channel Islands that were generated by the Army Map Service in 1943 from some of the very first aerial photogrammetry done in the US (Wonder why the Army was so interested in maps of the coast back then?).
Answering an old question I missed before. I can't be sure about this, but is it possible that they were experimenting with making maps of the European coasts prior to d-day? 1943 would be about the right time, and I would think it would have been much easier to do map experimentation on friendly coastlines. Just a thought.
