If we look at the archive, there is considerable discussion about these losses:

You will note that towards the end Peter Cornwell states:
"Photos have now emerged that indicate P3426 was NOT the aircraft flown by SHREWSBURY of No.85 Squadron when lost on 20 May 1940 as I have recorded in BoFrT&N."
I do kind of agree with Stig when he says that he can't see how the pilot would have been killed in that incident. Not impossible of course though.
I'm also not totally convinced that P3426 wore any code other than B. Bear in mind that this aircraft didn't seem to have any known service other than with Tangmere Station Flight, so it might be unlikely to have worn the 85 Sqn VY- code.
Does anyone know what code sequence was actually used by Tangmere SF?
