Was he given clearance to go on the runway, and if so, is the ATC person who gave that clearance still alive as of now?
At a time when there are international sanctions against Russia for invading Ukraine, look at who is there trying to weasel... the French. Just like with Saddam Hussein.
This is immensely embarrassing for Putin.
Yup. You're obviously familiar with air ops.
It wouldn't matter if the driver was drunk, stoned and on heroin simultaneously; if he was cleared at the same time as the aircraft, it's on the tower. Even if he wasn't cleared the tower should have had situational awareness.
In my experience, most airfield/runway snafus are caused by idiots in the tower. Then again, who knows how they do things in Russia.
