If I've read the brasilian press correctly, it was the 'senior' TAM pilot who was PF.
I remember from the Air France A340 toronto accident, that the PNF couldn t get to the throttles to apply REV because the PF was holding them firmly while he was trying to keep the aircraft on the RW. (heavy wind) Could something similar have happende here, so that the PNF (junior pilot) couldn't see that the other TL was not at idle?
