The BEA are currently involved in three investigations of serious incidents involving takeoffs at Bogota.
The first is the aforementioned Air France A340's "abnormally long takeoff run".
The second is another similar incident, date unknown.
The third is an Avianca Peru A330 which rotated beyond the end of 13L last July and took out one of the lights, the runway having a reduced TODA due to work in progress.
