Hello,
If you look closely at the photo in post 4, you should see that both wings are still attached, the cross on the right can be seen and most of the left wing can also be seen still attached to the fuselage. So my opinion is that unless it is the tip of one of the wings then yes it is from a second aircraft.

This leads me to ask if other photos exist that show the other aircraft ?

On further look, the rudder in photo shown in post 1 is damaged, while that in post 4 looks intact ( or completely removed ) ?
