The final report is due to be released into the crash of an Air France airliner in June 2009, which plunged into the Atlantic Ocean off Brazil, killing 228 people.
An interim report last year listed instrument problems, weaknesses with the pilots, and an issue with pilot training.
M R Hall is a novelist and screen writer and has carried out extensive research into the crash.
He told the Today programme about the "sequence of human errors" which contributed to the tragedy.
