The Australian's US correspondent Cameron Stewart highlights Boeing's recent stock market turbulence as one of 'Wall Street's darling companies' take a hit following the fatal Ethiopian Airlines crash on Sunday. Opening at about 10 per cent lower, Mr Stewart says Boeing's shares were 'savaged' in the biggest fall the aircraft company has seen in 'almost seven years'. Boeing has said it sees no reason at this point to ground it's 737 MAX 8 fleet as several countries begin halting flights on the aircraft model.
