"Best" thing i've experienced so far was a Tu-160 that turned onto the grass after landing, colliding with a scenery radar truck. Wheels were on the grass, but its right wing was still blocking the runway when it got stuck there - but that did not impress the second AI Tu-160. Shortly after the second one touched down it caused a quite expensive crash with the first one, leaving Sochi unusable for all other AI Airplanes.
