Kruska,
I've never read any accounts by Hs-129 pilots, so all I have to go on are what has been written about the AC itself. Everything I've read comments upon the unfavorable handling characteristics of ALL Hs-129 variants. Some were worse than others, but none were very good. and I'm sure that some pilots did like the little beast, but that goes for almost every AC ever built.
The armor on the Hs-129, like that of the Il-2/10, was designed primarily as a defense against ground-fire, and unlike the armoured engine of the Stormovik, the twin engines of the Hs-129 were extremely vulnerable to battle damage...and twice as easy to hit.
I'm familiar with the 'Notjaegerprogramm', but I think you're still begging the question...Again, if the Hs-129 was such a superlative anti-tank weapon, why would the OKW have not demanded that it be excluded from the cut? I know that war against the Allied bombers was the first priority, but surely all those Russian tanks also had to be stopped if the Third Reich was to survive.
All things considered, the fans of the Mossie, Beau, Invader, etc have a stronger case against the B-25J than does the Hs-129. But then, I consider the anti-armor role a distinct category in itself. The kind of cannons necessary to reliably destroy armor are over-specialized for the task of strafing in general. At least until the A-10 came along...

PS: Too bad there's nothing out there by the Soviet pilots that fought against the Hs-129. Anybody got any titles?
