Anyone know further details ? (WWII aircraft accident images)

I’ve had these images for quite some time.  As I don’t have the Air Britain RAF Serials books, or indeed other reference works by registration or type to help, thought it might be interesting to share these images and see if more details of the service life of these aircraft, and a cause of the calamity that befell them can be brought to light.

Vickers Wellington II W5441/K:EP, which makes it 104 Sqdn (formed 01.04.41 at RAF Driffield, much of unit to Malta 10.41, although a home echelon remained at RAF Driffield then became 158 Sqdn 14.02.42 still at Driffield with :NP unit codes).  Clearly 10 bombing missions completed by this Merlin engined aircraft.  The images came in an album of mostly 1980s aviation photos given to me by a work colleague after her father’s passing, so I have no idea of a name or how/why he had large prints of this aircraft.  No caption or stamps on the rear of the images to help.  Would appear that one engine was stopped (props still straight), the other side still powered.

Z9550 Bristol Blenheim IV, individual aircraft code A.  Nothing more known to me.  Passed to me in an envelope of some 50 tiny prints, many fading to sepia, very many years ago by a work colleague, Gill Heyes.  He had served in the Army in the Middle East during the War, which could be a clue despite the waterlogged site.  Is the camouflage European or Middle East shades?  The majority of the images though were subsequently discovered to be mostly of the British Army in Mesopotamia in 1919 – so were presumably his father’s!  I was given them as there were a few aircraft shots from WW11, mostly of wrecked German aircraft, along with this Blenheim.  I’m told the German aircraft prints are relatively common as they were given away as morale boosting souvenirs.  I’ll add them to this thread if anyone would like to see them.  When I last saw Gill, which was after having rediscovered the images and realised their age and possible significance, he was suffering from dementia and unfortunately unable to recall anything useful regarding their provenance.

Avro 504K H2277, somewhere in the Middle East, likely 1919.  Would be a classic atmospheric ‘in theatre’ shot, if not for that elbow!  Don’t realistically think that any detail for this aircraft could ever be found.  Just thought that as I had it in the same image file it would be nice one to share.
