Which door? In that area there were no doors, only a couple of small round (or oval in case of the upper one) fuselage hatches, whereas the area removed is not a panel, but a whole section of the fuselage...

Also, I think we should not apply too much of hindsight logic in case of abandoned, looted or rotten aircraft, because these were subject to the most various experiences, from "souvenir hunters" to metal scrappers, to simply vandalic issues done both by civilian and military alike (take a look at a video on-line showing US troops brutalizing the poor remains of a Bf 109 with hammers, hatchets, and even a baseball bat!).

Such planes, which today for us are precious remains of historical importance, at the time were simply pieces of metal emblazoned with enemy insignia, often a perfect target to let off some steam for people who until a few days or weeks before had risked their lives or lost friends fighting against them or had suffered under them.

In the best cases, those items were simply seen as a way to find some useful or profitable use and as a sort of compensation for the damages (either moral or material, or both) sustained.

IMHO, of course.
