The air part of the parade in Moscow has been cancelled due to bad weather. This is reported by the russian media.

They note that for this reason, the widely announced flight of Il-80, which is called the “doomsday” aircraft in the West, over Red Square has been cancelled.
Earlier, the Russian Ministry of Defense stated that the Il-80 would fly over Red Square on May 9. This aircraft is designed to evacuate the country’s top military leadership, as well as to control the rf Armed Forces in a full-scale military conflict, including a nuclear war.

Bleu sky is called bad weather…………………..everthing in The Russia is upside down.
In many cities it was ‘bad weather today’in The Russia….meaning very sunny day.
If the “doomsday” emergency plane can’t handle a few clouds how will it handle a real doomsday?
Weather was sunny in Moscow. Their excuse was it was cloudy at the airfield. Methinks they didn’t have any working planes.
And all the real pilots are dead,
