Erg.KG4, 31.07.1940

[srob48]

Apologies if this has been asked before (I did do a quick search and couldn't find anything on here).
I am looking for the crew details of the following aircraft which crashed on 31st July 1940:
Erg.KG4.
Heinkel He111P. Domestic flight, crashed on landing at Pinnow A/F, Poland. 4 NCO’s killed. Aircraft a write-off.

[Peter Cornwell]

Names of four casualties not recorded as far as I know but I show the unit as 9./KG4.

[Merlin]

I have the unit also as 9./KG 4 but III./KG 4 was during July 1940 equipped with the Ju 88A and was based at Schiphol.

I assume this was a loss of Ergänzungsstaffel/KG 4 (home base Faßberg) during a training flight to the Baltic Sea coast with a crew of 9./KG 4.
