"Whatever the reasons (market pressures, rushing processes, inadequate certifications, fear of being fired, or poor project management), Leveson’s insights are being ignored. For example, after the first fatal Boeing 737 Max flight, why was the entire fleet not grounded indefinitely? Or not grounded after an Indonesian safety committee report uncovered multiple failures? Or not grounded when an off-duty pilot helped avert a crash? What analysis procedures failed to prevent the second fatal Boeing 737 Max flight?"
