I saw an Aeroflot A320 taxi out at Oslo in heavy snow having heard him refuse de-icing. Following aircraft in the queue at the hold told the tower to inform him he had snow on the wings, which they did. He acknowledged it, then took the take off clearance.
jonseagull, can you recall date and time?
JCviggen, thanx for sharing! Do you remember actual time of takeoff?
Anyone who also remembers such instances with Aeroflot, please come forward and post info here. It all will be forwarded to numerous aviation authorities.
