One billion dollars - that's what Boeing says is the financial damage so far from two deadly airline crashes involving its bestselling 737 Max jet.

In announcing its quarterly earnings Wednesday, Boeing abandoned its 2019 outlook, halted its planned share buy-backs, and cut production and deliveries of the 737 MAX.

Anti-stall software in the 737 MAX is a suspected cause in the crash of an Ethiopian Airlines flight in March and a Lion Air flight in October, that killed a combined 346 people.
