A growing number of aviation regulators are grounding Boeing 737 MAX 8 aircraft, as investigators examine the wreckage of the doomed Ethiopian Airlines plane.
Countries around the world are closing airspace to the Boeing the 737 MAX 8 model after its involvement in the crash, the aircraft's second fatal accident in less than five months.
The US-based manufacturer, says it has no reason to pull the popular aircraft from the skies. It does not intend to issue new recommendations about the aircraft to customers.
Mr Trump tweeted manufacturers of new products, including aircraft, were "always seeking to go one unnecessary step further, when often old and simpler is far better".

Boeing's technical team joined American, Israeli, United Arab Emirates, Kenyan and other aviation experts in the investigation led by Ethiopian authorities.
Safety experts cautioned against drawing too many comparisons too soon with that Lion Air crash in October in Indonesia that killed 189 people.
Mr Trump did not specifically mention the crashes but said that "I don't know about you, but I don't want Albert Einstein to be my pilot."
The Ethiopian Airlines plane crashed six minutes after taking off for Nairobi.
One witness told The Associated Press he saw smoke coming from the plane's rear before it crashed in a rural field.

"The plane rotated two times in the air, and it had some smoke coming from the back then, it hit the ground and exploded," farmer Tamrat Abera said.
The Associated Press reports it will take five days before any victims' remains are identified.
