Are there any statistics available for how often there has been a need for a pilot to disengage MCAS? If we speculate (e.g. before the facts are in) that this was similar in cause to Lion air incident, then I would be curious to know how often AoA sensor has malfunctioned and|or MCAS has otherwise gone haywire and pilots have needed to revert to manual control during the two years of service MAX8s have had.
