Boeing said on Monday that it plans to temporarily suspend the production of its 737 Max jets next month to focus on clearing out the 400 or so aircraft currently grounded in storage.

The jets have been gathering dust since March 13, 2019, when America's Federal Aviation Administration (FAA) issued an emergency order grounding all 737 Max models in response to two crashes with the new aircraft that killed a total of 346 people.
