Nepal’s PM Pushpa Kamal Dahal has declared a national day of mourning as more details come to light about the plane crash in Nepal that killed at least 68 people – including young Sydney man Myron William Love. Authorities say it’s unlikely any of the 72 passengers and crew survived the 27-minute Yeti Airlines flight from Kathmandu to the tourist town of Pokhara. Some experts believe the pilots lost control of the aircraft, but the cause of the incident is still under investigation. Videos of the plane rolling sharply before it plummeted, along with eyewitness accounts, have emerged. Those accounts will be part of the investigation, along with the black boxes aviation authorities say they’ve recovered. Nepal has a poor airline safety record, but the latest crash is the country’s worst in over 30 years and its 3rd deadliest ever. Poor regulation standards have seen Nepalese airlines banned from European Union airspace since 2013.
