I have commuted on the Chartres Dreux road for years without knowing this. There is nothing but fields in between those towns. However there is an airfield still in use south of Dreux and another one west of Chartres on the road to Paris. If you go slighty towards the east while driving from Chartres to Dreux you will get to Nogent which was another field and most of all Maintenon, which was a major amno depot and Luftwaffe headquarters (Chateau) .
