Just as a funny picture of this, here you can see a iL-2 track in which a row of 20 T-70 tanks shoot a flying Stuka. Same happen with Panzer-III and Il-2, for instance.
After 3 minutes of shooting, the Stuka gets her tail and leg blown off. At minute 6, another hit blows her wing.
Given every tank is shooting more or less every 6-8 seconds, in total about 500 tank shots were needed to hit severely the plane, and another 500 to shot it down (25 shots/tank for first hit, 50 shots/tank the final hit).
Good aim, isn'it?
