Yak-9T - incredible firepower (or maybe incredible tank's lack of armor?)

[Torsteven]

Between 6 and 7% of German tanks were lost directly to air attacks during the Normandy campaign.

And for Panther:

The effect of Allied airpower is exaggerated to some extent. The direct effect seemed to be not that important. More effective would have been indirect effects, like the influence on tactical behaviour of the Germans and the interdiction of supply routes. From three British studies on Panther tanks found by British forces.

From 6 June 1944 till 16 January 1945 the “cause of death” was:
Armour piercing rounds: 63
Hollow charge projectiles: 8
HE rounds: 11
Aircraft rockets: 11
Aircraft cannon: 3
Destroyed by crew: 60
Abandoned: 43
Unknown: 24

So, the main threat to a tank was anti-tank gun !

P.S: Sorry for my poor English.
