JAKARTA—A “ping” sound believed to be emitted by the black box of an Indonesian jet that crashed into the sea this week with 189 aboard is getting clearer, the deputy of a national transport safety committee said on Nov. 1.
Ground staff lost touch with flight JT610 of budget airline Lion Air 13 minutes after the Boeing 737 MAX 8 took off early on Monday from Jakarta, on its way to the tin-mining town of Pangkal Pinang. There were no survivors.
