More nations ban Boeing 737 MAX jets after Ethiopia crash

The EU closed its airspace to Boeing 737 MAX planes on Tuesday, joining similar action by nations across the globe following a second deadly accident in just five months.

Fleets of the best-selling workhorse plane were also grounded by airlines as safety concerns swirled, sending Boeing shares tumbling another seven percent in Tuesday trading and wiping billions more off its market value.

On Sunday, a new Ethiopian Airlines 737 MAX 8 went down minutes into a flight from Addis Ababa to Nairobi, killing all 157 people on board.

In October, a Lion Air jet of the same model crashed in Indonesia, killing 189 people shortly after takeoff from Jakarta.

The widening airspace closures puts pressure on Boeing, the world's biggest planemaker, to prove the MAX planes are safe.

The full extent of the impact on international travel routes was unclear, although there are some 350 MAX 8 planes currently in service around the world with more than 5,000 on order.
