I also believe that the accident landing was carried out not by the ex-737 pilot but by the senior TAM training captain?
There was earlier a flight from Belo Horizonte to Congonhas and the crew landed with one TL in Reverse and the other on Idle.
Then the accident crew took over, went from São Paulo to Porto Alegre and back. They landed in Porto Alegre OK. The second pilot was the one who flew before for Transbrasil in 767-200 and 737s. He was with TAM for 6 months in training for A320s and was recently promoted to comandant. The other had been with TAM since 1987 and was getting ready to retire.
