Brian, no prob

Graham, let me check Hurri_II vs. Yak1... my guess would be that the Yak is more agile and the LaGG has a higher v_max.
Thank you, Mirek! The part about 235 IAD is very interesting!
Alltogether, all your inputs help (me) to get quite a better picture about the Hurries life in the USSR. Thanks!
