The United States will no longer fly the Boeing 737 Max 8 and Max 9 after an Ethiopian Airlines flight crashed Sunday shortly after takeoff from Addis Ababa, killing all 157 people on board.
President Trump said he was grounding them flights from both models - 'effective immediately' - on Wednesday afternoon.
Any plane that is currently in the air will be allowed to land and then they will be grounded until further notice, he said.
Trump said he made the decision after following a with Elaine Chao, the transportation secretary, after new information emerged on the tragic crash.

YES... I wonder how the Pilot was trained to handle that situation? The MCAS software issue does not cause debris to fall from the plane in flight!
We are dealing with EMOTION and not facts here. Please get the Black Box data then we can deal with some facts!
I think President Trump may be providing cover for Boeing.
AA 191 was in 1979 (fwiw)
On AA 191, the maintenance crew was using an unauthorized procedure (and perhaps forbidden) method to reattach an engine.
The proper procedure was to attach the engine mount (pylon) to the wing. THEN attach the engine using the proper lifting devices.
As I recall, maintenance put the pylon on the engine (wrong) THEN used a forklift to left the entire assembly to the wing and attached it. This caused damage (perhaps to the bolt you are referencing). I DO remember the bolt.
They found out later that wasn't the case.
Apparently there was a shift change during engine maintenance and the forklift was left unattended.
IIRC, the hydraulics on the forklift gave way during this time, and it ended up damaging the engine/wing.
But some spokesman came out and claimed it was a single bolt.
And the rumors started.
[THEN used a forklift to LIFT the entire assembly to the wing and attached it]
oops
Interesting...never heard that cause before. Was that listed as the final cause? As I recall, the engine DID drop off the plane.
“Democrats criticize Trump for allowing Americans to remain on defective planes”.
As the left engine flew forward, it severely damaged hydraulic lines to the flight control surfaces on the left wing.
Some said the engine went forward and over the wing. I’d have to look at the pics again to see if the pylon was still attached (whatever was left of it).
The slat, or leading edge of the a/c retracted due to loss of hydraulic pressure. The crew performed the normal engine out procedure and reduced power. However, with the left slat retracted, still too much lift imbalance caused the a/c to roll left beyond recovery. The crew would not have been able to see that the engine had separated.
I had heard the L-1011 locked the slat in place and that the DC-10 did not have this as a feature. Not sure if this was altered on DC-11/12 a/c.
[Some said the engine went forward and over the wing]
IOW, the engine goes forward quickly now that it is unattached. After the fuel in the lines is gone, the airflow pushes the engine over the wing and it hits the ground.
Or so that was the claim.
I believe that was 200 hours in type. Not total hours.
“If they actually tried to “stick and rudder” it, it would be impossible for a human being to keep it from crashing.”
They landed the first couple flights manually.
“A reasonable guess is that the center of gravity changes enough to make it unstable.”
No that is not close to ‘reasonable’. Engineering mistakes may have been made but that one is not at all likely.
Yes a bomb or a possible missile strike has a kind of sobering emotional draining effect when it first happens and they aren’t caused by faulty sensors or software.
Debris flying off a plane after a loud “noise” with black smoke streaming from it prior to a crash makes me wonder who was on the plane that somebody may have wanted dead!
I saw it on some airline crashes special.
According to Wikipedia, it was a combo of procedures, like SaveFerris mentioned above. The plane apparently flew eight more times before the Chicago crash.
The engine (unknowingly) kept rocking back and forth until that flight where it broke completely off from fatigue.
Also from Wiki: Apparently, if the pilots KNEW what happened they should have "theoretically" been able to land with the other engines.
But I think it happened too fast.
May 25, 1979, United Airlines flight 191.
I remember the detail because my uncle died in a separate air crash on that same day.
It was United Airlines flight 191.
Would Freepers who know ABSOLUTELY NOTHING about aerodynamics please refrain from making comments while an NTSB investigation is still underway?
Instead, use your time reading up on the extensive certification process for commercial airliners.
Yes, a few later generation fighters are dynamically unstable to enable more extreme maneuvers. (The F-16 comes to mind) However, Transport aircraft are exactly the opposite.
There is "blood in the water" and the shark lawyers will be getting into a frenzy at the thought of suing Deep-Pockets" Boeing.
Then follows all of the MSM Talking HEads seeking a Pulitzer Prize.
Lastly come all of the "outraged" Congress Critters looking for TV time to enhance their Presidential Campaigns.
[It was United Airlines flight 191.]
No. It wasn’t. That’s why I call it AA 191. Here’s some more info:
American Airlines Flight 191

Sorry to hear about your uncle, BTW.
A guy I worked for (much later) was arriving at O’Hare that day for training. He arrived just after the crash occurred. Saw the smoke.
