An Air Asia flight QZ8501 has lost contact after take-off from Surabaya in Indonesia, and is still to be traced by air traffic control.
Fears have risen for the lives of the 162 people on board as search operations continue.
The news has evoked memories of the MH370 tragedy, when the Malaysian Airlines plane disappeared off the radar earlier this year, and has still not been found.
Netizens on social media expressed grief and anger over the latest incident. Under the hashtag #QZ8501 that is trending worldwide on Twitter, Twitterati extended prayers for families of those on board.
AirAsia itself shared a handle for netizens to direct enquiries to about the missing flight. "Dear Guests, for Customer Care enquiries please drop a tweet to @askairasia for assistance. Thank you," the airline tweeted.
