Boeing has not said yet when it plans to resume production of the 737 MAX, but has indicated it will be gradual and under regulatory scrutiny. The plane maker has racked up losses of nearly $8 billion this year as it continues to wrestle with a quality crisis from a January mid-air panel blowout. "We have hard work ahead to restore our company and deliver on our customer commitments, but we are on the right path and making the right changes," Ortberg wrote. Boeing raised $24 billion in fresh capital last month to shore up its finances. Ortberg said last month he is reviewing Boeing's businesses and long-term forecasts. The company may end up selling some assets, as it downsizes its workforce to focus on the company's key civil planemaking and core defense units. Ortberg's email was reported earlier by the Air Current, an aviation industry publication.
