Congratulations Flap40!
It is indeed Lyon-Satolas or more precisely Lyon-Saint-Exupéry. The photo was showing the still visible runway of ALG Y-34 which is now like properly indicated by Flap40 lying under other constructions and rubble in the SW corner of the airport footprint.
The Y-34 airfield saw use in Sept 1944 with the F5 Lightning of the 23rd Photo Reconnaissance Squadron and the F6 Mustang of the 111th Reconnaissance Squadron.
You have the helm Flap40!
