The London Mail online published a series of WWI military photos superimposed on downtown London photos.
One of the photos is shown above showing a WWI German airplane with the wings removed. It appears to be an Albatros C.III.
The two-place Albatros C.III was used by the German Army during the early part of WWI for observation and photo-reconnaissance duties. It was a slow flying plane, even by WWI standards and was limited to low altitude duty.
It could not have been very maneuverable with such a small vertical tail.
