After experiencing a series of crises, Boeing is considering selling some of its space business to improve the company's tense situation. At present, Boeing is facing a serious financial crisis. Just last week, Boeing workers voted to reject the company's latest contract offer, extending the strike again and causing most aircraft production to continue to stop. At the same time, the company also announced its worst quarterly performance in history, with a cumulative loss of up to $6 billion in the third quarter.
