After two deadly crashes involving the same jet model, Boeing will make standard a feature that it had charged for, as part of an effort to get the planes in the air again. Neither of the planes that crashed in Ethiopia and Indonesia was equipped with the feature, which is not required by regulators.

Yesterday: The Defense Department said it was investigating complaints that the acting defense secretary, Patrick Shanahan, had been promoting his former employer, Boeing, and disparaging its military contractor competitors.

Go deeper: Investigators in Indonesia described confusion and prayer in the cockpit before the Lion Air crash in October. “God is great,” the co-pilot prayed.

Federal Reserve downgrades its forecast

Saying on Wednesday that the U.S. economy was slowing more than it had previously thought, the central bank left interest rates unchanged and signaled little appetite for raising them in the near future.

The Fed said that growth appeared to be slowing under the weight of the trade war, economic slowdowns in Europe and China, and fading stimulus from the tax cuts of 2017.

What’s next: The central bank expects 2.1 percent growth this year, down from the 2.3 percent it forecast in December — and more than a percentage point less than the 3.2 percent growth predicted by the White House. In 2020, the Fed projects growth of 1.9 percent.
