"Angriffshöhe 4000" - Opinion needed

[Christer Bergström]

I don't agree that it is a a must-own book. There simply are far too many errors in this dated book (1963). Plus that it seems to be biased. I would rather recommend E. R. Hooton's "Eagle in Flames: The Fall of the Luftwaffe" (1997), which deals with the same subject, but with today's access to archive material and without any bias.
