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

[Janosch]

I don't remember Rudel making such mistake about the sirens, but then again it's been a while since I read the book. I do remember that he misremembered some Soviet plane designations though. It's still a great book, I had some great laughs reading it (not because of the content or errors, but emotion and style)!
