Just had to evacuate my flight to Perth after engineering issues. Everyone had to exit the plane via slide onto Sydney tarmac after the cabin filled with smoke and the captain screamed evacuate. Terrifying.— Ally Kemp (@politic_ally) December 14, 2019
According to SBS news, the captain informed passengers about the problem and ordered the evacuation.
