So the physics of a round firing from a cannon intersecting an aircraft and destroying it should not be possible in this game because you can't find an instance where it actually occurred?
Hmm . . . then please find me a source that says a KI-84 once shot down a N1K-2. If you can not find it, then i want those pesky KI-84 rounds nerfed when flying my orange target around.
Oh, and here is a link (hope still valid) to a rather long article, but I'll quote the relevant section for those who think tanks didn't use their main guns to shoot at aircraft. I'll also bold some relevant advice to those of you complaining about being shot by tank main guns.

"We even used our main gun against aircraft. We placed the tank on the upslope of a hill and fired."
Did they actually hit many? Probably not.
One thing is IRL you didnt have the same SA we have here. Here the commander,driver and gunner are all the same person. Therefor they all have the same SA.
Try just sitting in the gunners position and locating,aiming and then firing at a fast moving AC. Its alot more difficult and most shots you get to shoot as are more luck then skill. Just locating an AC would be as much luck as anything. then you have to train your gun and fire.
Here as I said. The commander,driver and gunner are all the same person You can jump from position to position and instinctively know where to move,look point and aim in a nanosecond. IRL they didnt have that kind of SA.
Also. we are talking 1 gun here. It was hard enough for a ship with a complete compliment of AA weapons many times more then a tanks single gun at its disposal to hit aircraft. And they still didnt always bring them down even with several ships firing on them. And they had the added incentive of their actual lives being on the line to not miss. I find it highly improbable that tanker even with the kind of experience we have here in game that a tank would have shot down an aircraft coming in at any angle as easily as its done here in game.
All of that is equally amusing to me because its far easier to hit an AC here with a tanks main gun with a single shot then it is with most AA guns here which have a by far a faster rate of fire.
but as I mentioned in an earlier post. Its a balanced tradeoff when you consider there are some planes here that take out tanks with far greater ease then they ever did IRL. Mostly due to the zoom feature which they didnt have IRL.
