Two Australians were among the 150 killed in the Germanwings Airbus A320 plane crash in the French Alps, Foreign Minister Julie Bishop confirmed today. A plane operated by Germany's budget carrier Lufthansa crashed in a remote area of the French Alps yesterday, killing all on board in France's worst aviation disaster in decades. "Sadly, I can confirm some heartbreaking news that two Australian citizens, a mother and her adult son from Victoria, were on board this Germanwings flight that crashed in a remote area of the southern Alps in France," Bishop said in an interview here.
