An investigation is underway after a Boeing 737 MAX 8 aircraft crashed Sunday in Ethiopia, killing all 157 people on board.
It is the second time in less than six months that one of the planes has crashed within minutes of takeoff, after a new Lion Air Boeing 737 MAX 8 flight went down over the Java Sea last October, killing 189 people.
Both crashes are under investigation and there is no evidence of a link between the two, but similarities between the incidents have prompted caution among some aviation authorities and airlines.
There are approximately 350 Boeing 737 Max 8 aircraft in operation worldwide, being flown by 54 operators, according to the US Federal Aviation Administration (FAA).
Travelers can check the full list of airlines that fly the plane on the Boeing website.

On Sunday, the US aviation authority said it would help Ethiopian authorities investigate the crash.

“The US Federal Aviation Administration (FAA) is responsible for certifying all Boeing 737 Max 8 models and it is the European Aviation Safety Agency (EASA) that validates this certification across the EU, including the UK,” said the spokesperson, who said that the CAA is working closely with the EASA.
European Union Aviation Safety Agency (EASA)
EASA said it was monitoring the crash investigation closely.
“We will immediately publish any further information on our website as the necessary information is available,” a statement from the agency read.
