This won't give you a full-on blind fog, but pilots did'nt fly in such conditions in WWII anyways.

Hi Murph, the reason for this request is posted above. 325th P-47's on a mission below radar were enclosed in a dense sea fog and flew on at 50-feet using instruments only (complete radio silence). 300-miles later, all 61 aircraft rose out of the fog. Jerry Edwards flying P-47 #38 (Alp Scalper) that day said he couldn't believe that everyone made it as they had been told if they needed to ditch, they were not to break radio silence in-case it alerted the enemy. His words "our leader that day did a hell of a job!"

Cheers, MP
