I'm pretty sure the cartoon was never meant to be drawn to scale. You are correct that it appears that the plane went under the wing from the video, but the angle can be misleading. However, the crew reported that the cirrus went under the wing. I'm almost positive that the tug driver alerted them to the fact. He/she would've had the best vantage point.

If the excuse for the diagram being misleading is that it was never intended to be accurate, one wonders why they bothered to show it.

Donˋt know what is the fuzz about. The Cirrus is a low wing airplane with maximum height of 2.73m which is the tail. The SR22 Pilot taxiing has a perfect visibility to all relevant parts of his plane. A320 wing clearance on the outside is 4m. The danger and responsibility to run into something expensive is sole with the Cirrus pilot. So unless he tries to pass under the body or engines of the A320, nothing will happen. The prop blast of the Cirrus at taxi speed will not blow away the A320. So what is the problem here?

:ok:indeed ! plus possibly someone ego having been stepped on ..

That looks like a 91.13 whether or not he was in a non-movement area
