Boeing cooperated fully and extensively with the Committee's inquiry since it began in early 2019. We have been hard at work strengthening our safety culture and rebuilding trust with our customers, regulators, and the flying public. The passengers and crew on board Lion Air Flight 610 and Ethiopian Airlines Flight 302, as well as their loved ones, continue to be in our thoughts and prayers.
Multiple committees, experts, and governmental authorities have examined issues related to the MAX, and we have incorporated many of their recommendations, as well as the results of our own internal reviews, into the 737 MAX and the overall airplane design process. The revised design of the MAX has received intensive internal and regulatory review, including more than 375,000 engineering and test hours and 1,300 test flights. Once the FAA and other regulators have determined the MAX can safely return to service, it will be one of the most thoroughly-scrutinized aircraft in history, and we have full confidence in its safety. We have also taken steps to bolster safety across our company, consulting outside experts and learning from best practices in other industries. We have set up a new safety organization to enhance and standardize safety practices, restructured our engineering organization to give engineers a stronger voice and a more direct line to share concerns with top management, created a permanent Aerospace Safety Committee of our Board of Directors as well as expanded the role of the Safety Promotion Center.
We have learned many hard lessons as a company from the accidents of Lion Air Flight 610 and Ethiopian Airlines Flight 302, and from the mistakes we have made. As this report recognizes, we have made fundamental changes to our company as a result, and continue to look for ways to improve. Change is always hard and requires daily commitment, but we as a company are dedicated to doing the work.
