Boeing stock tumbles after its 737 plane goes down in Indonesia

Aerospace giant Boeing’s share price dropped nearly 7 percent Monday after one of its newest planes careened into the Java Sea off the coast of Indonesia with 189 people on board.

The new Boeing 737 Max 8 was operated by Lion Air, the Indonesian budget airline that has emerged as an important international customer at a time when the Chicago-based company is hoping to expand its sales in Southeast Asia.
