The crash could renew scrutiny of Boeing, which suffered a major blow to its reputation after 2018 and 2019 crashes involving its 737 Max planes.

Black box data has been decisive in solving major aviation disasters globally, ranging from the 2015 Germanwings crash to various Malaysia Airlines incidents. In India, the investigation into the 2020 Kozhikode crash relied heavily on these recordings to establish pilot decisions and runway conditions during the failed landing attempt.
