The families of passengers lost aboard Malaysia Airlines flight MH370 say the two-year search for the missing aircraft must go on beyond a June deadline, as new hope emerged last week of resolving the aviation mystery.
Debris found off the African coast rekindled hope for many, prompting relatives like Grace Subathirai Nathan to demand investigators go back over mistakes made early on.
"A lot of it was based on calculations that had never been used before, where there's room for human error," Nathan said in an interview. Nathan's mother, Anne Daisy, was on board when MH370 disappeared on its way to Beijing from Kuala Lumpur on March 8, 2014, with 239 passengers and crew on board.
Some 120,000 sq km (46,300 sq mi) of the sea floor is being scoured at an estimated cost of about A$170 million ($124.17 million). But no trace of the missing Boeing 777 has been found except for a wing part, known as a flaperon, which surfaced on Reunion island off Madagascar last July.
