Those aren't Jatos. That's exaust form the Gas motors. . . and I think you're looking in the right direction -- it doesn't look like his left wing was pulling like it should.
If you look at the control surfaces, he was fighting it's drift and roll from the start of roll-out, and it simply wasn't responding to the surface inputs. Something was wrong with the motors, and after it drifted off centerline, if he had aborted it would have gone into the crowd.
My sympathy to the Mac for the damage, Kudos to him for doing everything right that he could, and praise to God nobody got hurt.
