I recall Crump arguing that the Spitfire could not follow the Fw190 in a climp because the Spitfire climbed at ~4,500fpm at 170mph and the Fw190 climbed at ~3,750fpm at 190mph. He could not grasp that the Spitfire's climbrate at 190mph was still better than the Fw190's and it could just lower its climb to match the 190's. He insisted that the angle of the climb would be off and the Spit couldn't get a gun solution that way.
He didn't understand how the Fw190 had to utilize its speed and climb to escape from the Spitfire. He thought it happened at best climb speed, not at the point where the Spitfire had no spare thrust and the Fw190 still had some, 321mph at sea level for the Mk IX, 338mph for the VIII, 344mph for the XVI and 358 for the Mk XIV. Well, a bit sooner as the Fw190's excess thrust would exceed the Spit's before the reached their max speed, but you get the idea.
I recall this debate, I was probably in it. Good memory you have Karnak.
Anyway, I was always rather in a good contact with Crumpp, we even flew together. We also had jostling debates with Izzy on numerous occations.
He did have good sources as well, but no sources are complete (normally) and then you need the head as well as the historical knowledge to compile the whole heap, - up to some sense!
I recall a thread where Crumpp sort of snapped, and went all mad at Widewing, I think I even posted something there. Sort of baffled me.
Later on, there was a BoB or something of the sort-Thread, where he really baffled me again with complete lack of comprehension. I think Scholzie may have been touching those issues as well as many others...now was it the BoB or the Graf Zeppelin (CV) thread.
Anyway, shortly after Crumpp was banned, and he did not show up again.
I had a BoB debate prepped for him, so I found it a pity (

), and we never got on to the subject per email or otherwise.
So, no bashing here, just looking back a bit, and I rather have the opinion that it would have been better for at least Crumpp to stay on the forum, just like you....Viking.
