I was holding short for 22 when he landed. He told the tower he had blown a tire. If I remember correctly, she came back and told him he was smoking. He then asked if they were on fire and got no response. Another plane came on and told them they were on fire, and they immediately came back and said they were evacuating. We were wondering why they were circling to 22 when everyone else was landing 12R. That helicopter just happened to be approaching the field when he landed. Total luck on their part.
