Having had the misfortune to have done some transcripts of fatal air accidents, I can assure you that it takes longer than you would think and is more draining than you would think - especially when you know the people involved. Add in chaotic ECAM and cavalry charges and alarms etc etc and I am surprised that they have done as much as they have.
All the time you are aware that someone will challenge your transcripts so you go over and over. Each alarm has to be identified, each sound identified. Not a pleasant task at all.
