Bonjour
Selon le site cet aérodrome ne serait pas opérationnel avant
juin 1944.
Mais les infos sont-elles exactes ???
Avallon (FR) (c. 47 29 N – 03 54 E) General: former landing
ground in C France 88 km WNW of Dijon. No further
information or evidence of use by the Luftwaffe found.
Apparently inactivated after the 1940 campaign in France.
Mattiello states that it was operational in June 1944.
