1940 or 1941?
 

Please can someone confirm the correct date of this accident?

Erg.(F)/Ob.d.L Döberitz. Lt. Stephan-Stefan Niesert killed. Flugzeug accident and died in Wollstein Hospital, Warthegau, Poland. Lt. Johann Jakob Friedrich Bomhard (B) killed. Flugzeug accident and died in Wollstein Hospital, Warthegau, Poland.

Unfortunately, one Ancestry says "27.06.1940" and another Ancestry card says "27.06.1941".

Any other loss details would be most appreciated, Aircraft type etc.
