The french IGN website has a bunch of aerial photographs taken just after the war. The earliest picture they have of the fields in question, were taken in
1947.
Sommervieu airfield, although abandoned and returned to the former owners, can still be recognized (lower part of first and second picture)
"old equipment park" and "new equipment park" have been cleaned of any remaining kit so it seems...and basically both fields look like they did in May 1944.
