This from Marcel van Heijkop:
I was informed a couple of days ago by Andreas Zapf that Me 262 expert and author Manfred Boehme passed away on 24 February 2026 at 91 years of age. May his books and memory live on for ever!
Members may know his books on JG 7 (published in German and English) and on NAGr. 6 (German only, as far as I know).
