737 Max

We have just been alerted to the news that President Trump and the FAA have grounded all Boeing 737 Max-8 and 737 Max-9 airplanes immediately and they will be out of service until further notice.

The impact of these groundings should be minimal. Southwest Airlines employs 36 of the grounded aircraft, while American Airlines flies 24 of the planes.

An ABC News announcement was made and includes the following:

ABC NEWS ANNOUNCEMENT

President Donald Trump announced today that the FAA would order the immediate grounding of all Boeing 737 MAX 8 and MAX 9 aircraft in the U.S., a decision that comes after days of mounting pressure from other countries that left the U.S. as one of the last to make the call after a deadly crash in Ethiopia.

"The safety of the American people, of all people, is our paramount concern," Trump said, adding that the grounding would take effect as soon as the planes landed and would continue until further notice.

The president said the decision was made based on new evidence that had come to light.

"The FAA is prepared to make an announcement very shortly regarding the new information and physical evidence we've received from the site and from other locations and through a couple of other complaints," he said. "We've had a very, very detailed group of people working on the 737 8 and the 737 9 new airplanes. We're going to be issuing an emergency order of prohibition to ground all flights of the 737 Max 8 and the 737 Max 9 and planes associated with that line."

But in an important caveat, Trump said the decision to ground the planes "didn't have to be made" but was made for a number of reasons, he said, including "psychologically and a lot of other ways."

The president said he'd spoken with the Transportation Secretary Elaine Chao, as well as the CEO of Boeing, and the acting administrator of the FAA and that all agreed on taking the action.

And for the first time, President Trump directly expressed sympathy for the victims of the crash, calling it a "terrible tragedy."

The president also called Boeing an "incredible company." Just Tuesday, Boeing's CEO had lobbied Trump against any grounding but right after Trump's announcement issued a statement saying it supported the move.

"We are supporting this proactive step out of an abundance of caution. Safety is a core value at Boeing for as long as we have been building airplanes; and it always will be," the Boeing statement said.

Meanwhile, Ethiopia said it would transport the "black boxes" from Ethiopian Airlines flight 302 to another country, a decision that would speed up a delay in the analysis of critical flight data that could help explain the second deadly crash of a Boeing 737 MAX 8 plane in just five months.

Ethiopian officials said the country doesn't have the technology required to analyze the black boxes -- the flight data and cockpit voice recorders -- which hold key information on how and why the plane crashed on Sunday, killing all 157 people on board, ABC News Chief National Correspondent Matt Gutman reported from Ethiopia's capital of Addis Ababa.
