The aircraft (in the background on page 14) would appear to be a Bombay (above). I did wonder if it could have been a Free French aircraft, because while 84 were at Landing Ground 75, there was an accident (on a windless day) when three Blenheims of 45 Sqn took off at the same time as three Free French aircraft were taking off from the opposite end of the runway. Two of them collided and burned, but one stalled and crashed. I thought the latter could have been the aircraft in question. I also checked Italian aircraft on Wiki, but while there were at least five twin-engine types that had a twin tail stabiliser, they don't fit the appearance as well as a Bombay. Likewise for Free French. As MPN11 says, Bombays were being flown by 216 Sqn, as transport aircraft, in the area at that time.
Pity... I rather liked the idea of that aircraft belonging to the opposition. (Free French would have been not far behind
)
