Luftwaffe pilots shot while parachuted

[edgardo gil]

I read the vol.1 of JG 300 by Jean Yves Lorant and Richard Goyat and I´m reading the vol 2 and I´m astonished how many Luftwaffe pilots were killed while hanging on its parachutes.
I mean I know some histories about that, like a Bf 110 Luftwaffe pilot that kill a polish pilot during Fall Weiss in 1939 or that some USAAF members did this.
But reading these books, the frequency of that practice really astonished me.
I never read for example that the soviet pilots used this tactic on the eastern front.
Do you know another histories of german and other nation pilots doing this kind of killings?
