I guess this query is linked to the following case:

Battle of France Then & Now only covers operational units, so it possible a Do 17 of a rear area unit (training, ferrying, or service unit) crashed there. But I have not the loss lists corresponding.
Regarding the presence of a Wermacht officer aboard, it could have been on a "pleasure" flight, or it could also be a flight to check from the sky if his ground unit was well hidden (something that was done at times by French Army officers at least).
