And you know this how? Unless you were in the cockpit you're speculating. Could have been windshear that resulted in a pilot induced oscillation (yes, I realize that is speculation).

Bottom line the guy screwed up the landing, sucked up his pride, and went around. Much better scenerio than burning up the brakes or going off roading. I'm not seeing where pax were put in joepardy(sic).

Any landing you can walk away from is a good landing. Any landing you can re-use the airplane is a great landing.
