mittal solanki 260 1899 days ago NEW YORK: Boeing on Tuesday officially pushed back the timeframe for the 737 MAX to return to the skies, sending shares plunging and overshadowing an earlier announcement of a first flight of the delayed 777X plane. Boeing said it is now targeting the return of the grounded MAX "during mid-2020," the latest delay in the schedule for the troubled jet, which has been grounded since March following two deadly crashes.
