The document summarizes a landing overrun by a Qantas Boeing 747-400 at Bangkok airport in 1999. It identifies several factors that contributed to the overrun, including the pilots not using an appropriate risk assessment for the wet runway, confusion over thrust lever control during landing, and inadequate company procedures and training for landing on contaminated runways. After the incident, Qantas implemented several changes like improved guidance for pilots on flap and thrust settings for different runway conditions, additional crew training, and better communication procedures in emergencies. Monitoring since then shows pilots now select flap 30 more often and use maximum reverse thrust on most landings, with touchdowns closer to the desired point.
