Letzte Meldung/last message from: Jakobshagen, 03.1945
The informations for the VBL were providet by the famlies of the missing- these were often not up-to-date regarding units and/or the dates and loctions of the last known message.
About "We looking for next pilot:"
AFAIK the registriatrion of German gravesides in eastern Europe is still far away from beeing complete - if there ever was any registered burial place.
So there are some options regarding the fate of the Luftwaffe personal still listed as missing:
-They were never recovered
-they were recovered and are buried as unknown
-they were pronounced dead
-they were mentioned in the VBL, but returned from captivity or were recovered later
In the VBL of the JG-, ZG-, NJG-, SG- and NSG-units only there were around 350 persons listed as missing or sent a last message from nowadays Polish territory in 1945.
