You're making an assumption that the outcome would have been different if that wall wasn't there. You're wrong. 50m past that wall is another wall, 5m after that is a highway.
I dont think the plane would get pulverized hitting a brick wall, and the distance will also slow the speed.
And the highway is not above the plane's travel axis, so the highway is a non sequitur. Not to mention even more distance to slow down.
