According to the following website
http://ag-luftkriegsgeschichte-kreis...ellenthal1.htm, a Ju 88 C-6 of LBS 3 (Luftbeobachtungsstaffel 3) was lost during the night of 19-20 Feb 1944 at Kradenhövel, with the three crew being unhurt.
With no casualty as this date, there is little chance there will be a loss report but I will be interested to know more about this loss if someone has more details.
From what I have read Luftbeobachtungsstaffel were more used against USAAF daylight raids than against RAF night raids, so maybe this website is wrong by giving it as a night loss.
Thanks in advance
PS: both Balss books have nothing about this loss.
