Aircraft lost to arty?

[PzHeinZ]

I remember having read about an incident in which a Finnish WWI-era 203mm howitzer shot down a Soviet postal plane. It was somewhere between 1942 and 1944, which was time of trench warfare in Russo-Finnish front.

I guess these artillery guys had a little too much time and also a genius among them. The Soviet plane flew pass the frontline daily, same route, same time every day. So these guys started to make calculations on distance, speed etc. to hit the plane with a single heavy shell...so once they were ready and went for it, they hit the plane which disappeared completely in a huge explosion in the sky :cool2:...unfortunately I cannot remember the source where I read this but it was of type I could trust , even if this sounds unbelieveable.
