Theo,
A bit of local history here:
https://www.luchtvaartgeschiedenis.b...77-op-maldegem
The Wellington had landed practically unobserved (most guards asleep or elsewhere..).
Town people could all have a look on Saturday and were told the plane was captured as early as in 1939 in Poland, probably to cover up the absence of guards when it landed.
On Monday (10 Nov) the a/c was fueled up and departed for Germany.
Regards,
Leendert
