Germany's minister for transportation and digital infrastructure (yes, i know, weird combination) blocks the 738M from german airspace.
See this tweet (german) from the official twitter account of that department.

Turkish Airlines to ground their 12 MAXs. New user, can't post a link, just see the tweet by @yhyustun (SVP, press relations)
About TK’ operations with B737 MAX type aircrafts Turkish Airlines has stopped its operations that conducted with 12 B737 MAX type passenger aircrafts located in its fleet, until further notice. Concerning decision will start to be applied as from 13rd March 2019.
How many airlines did what American and Southwest did? I understand that both of those airlines have an installed option (why it's an 'option' I have no idea, I'll let wiser heads reflect on that) that gives the pilots AoA displays. Given that AoA signal appears to figure in this back up system's operation, seems a smart move to me. What puzzles me is why any airline would not, but I am biased since I believe that pilots are supposed to fly aircraft, not guess at what an aircraft is doing.
When I look at this system from a systems perspective, it is a back up system whose intended function is to avoid a stall/accident.
Fix one problem, raise another one.
Nothing new under the sun.
I saw an interesting observation here regarding the Brazilian Certifying authority.
I am not sure if they called for this before or after the Lion Air accident. If before, that leaves open, to me, the question of why didn't all certifying authorities, FAA, CAA, Chinese, Norwegian... all of them, make that same demand?
Again, this is my bias showing since I do not believe that something that moves the flight controls should be hidden from, or a mystery to, the pilots.

The Brazilian Certifying authority did, with Boeing's involvement, require MCAS training. What that training was would be interesting. I would assume somebody from GOL, a Max operator, would know what that was. If we find out we might know whether that type of training would have helped the Lion Air crew.

derjodel, would you care to elaborate? That answer is at best incomplete. (SW flies only 73's but American flies a variety of models. I've a friend who flies A320s for American).

CAA bans 737 MAX 8 from UK airspace.
https://www.google.co.uk/amp/s/www.b...-asia-47536502
this is an excellent move. A few days too late.

Airspace bans might be less associated with the aircraft - at least until there is more information on this accident, than in the confidence of the certification process.
Considering what is currently known about Lion, Boeing’s proposals for modification, and the FAA position, then many National Authorities actions’ could be questioning their trust in the Max certification.
Various posts have cited concerns, perhaps these have hardened.
An interesting thread around these aspects is developing in Tech Log Boeing advice on "aerodynamically relieving airloads" using manual stabilizer trim

Aerolineas Argentinas has also grounded the MAX fleet yesterday, waiting for some explanations from Boeing.

The post to which you were replying was asking why the CAA had issued their ban. Given that EASA followed suit a few hours later, the reason for it is fairly obvious, though there may be an element of the CAA wishing to assert that it is capable of acting independently of EASA, as it will have to do post-Brexit.

Has anyone questioned the ridiculous speeds (380 knots at one stage) while this plane was struggling? Were the flaps retracted, if not how could the airframe have survived this onslaught (correct me if I'm wrong max speed flap 5 is 180 knots). If the flaps were retracted, wouldn't that be suicidal at 900 feet?

Pressure is really building on FAA.
Senator Tec Cruz, chairman of a subcommittee on aviation and space is saying it would be prudent to join other regulators and thereby he is urging FAA to ground the Max.
He also say he intends to hold a hearing to investigate these crashes.
