That's the standard way for Hurri D's to die.
Just look at the numbers: Last tour the D killed a total of 104 Panzer IV's, but had 109 deaths by Panzer IV's. You can bet the overwhelming majority was not actively shot down by those tanks
I did get shot down by a Panzer today.
Came in at a steep angle and he started to ping me. The hits threw off my aim and as I was crossing over top of him, the pinging sound turned into that horrible damage "crunching" sound. I rolled over and went in.
"Alright you bastage."
I went back to exact my revenge and pushed it too far - WHAM! (trees, not George Michael)
On the third try, he hit my oil and when I finally got him, I towered and went to a base far, far away from that guy.
