Some of those demonstrate amazing investigation skills by those responsible bodies. I remember one where they discovered that a certain insect nested in the pitot tubes (airspeed measurement device), blocked them and caused a crash. I believe they are covered up now when an aircraft is static.I love watching those air crash investigation & there have been 276 episodes in 20 years. Although they are catastrophe and fundamental mistakes have been made, usually down to the aircraft companies priorising profit, it's less than 1% of planes in the sky at any moment
