Updated Jan. 12, 2021 6:34 pm ET The Sriwijaya Air jet that crashed on Saturday didnât fly for nearly nine months last year, with air travel severely reduced because of the coronavirus pandemic, Indonesiaâs transportation ministry said, as search crews pulled one of the planeâs so-called black boxes from the Java Sea. The Boeing Co. 737-500 was inspected and declared airworthy before resuming flying operations, the ministry said. The Indonesian carrierâs aircraft with 62 people on board went down minutes after taking off from the countryâs capital, Jakarta. There are believed to be no survivors. Divers and search crew, who grappled with sharp debris and low underwater visibility, managed to recover the planeâs flight-data recorder on Tuesday, an important early step in uncovering why SJ182 crashed.
