Concerns escalate as U.S. still hasn't grounded Boeing 737 MAX planes

Following the horrific Ethiopian Airlines crash on Sunday morning that killed all 157 people on board, the list of countries and airlines banning Boeing's aircraft is growing. But so far, the United States is not one of them.

The Ethiopian Airlines flight from Addis Ababa to Nairobi, Kenya, was a 737 MAX 8 plane made by Boeing, which is an American company. This was the second fatal crash of a 737 MAX 8 in the past six months.

Currently, forensic investigators are processing the site where the Ethiopian Airlines Flight 302 crashed. The airline's CEO, Tewolde GebreMariam, said the pilot of the flight reported something wasn't quite right in an exchange with air traffic control.

"The pilot reported flight control problems," said the CEO of Ethiopian Airlines. "So he was having difficulties with the flight control of the airplane, so he asked to return back to base."

Among the 157 that were killed was a 24-year-old woman who grew up in Massachusetts. Samya Stumo grew up in the Berkshires and graduated from UMass Amherst.

As we're learning more about the passengers who were on the flight, the pressure to ground the aircraft involved in the crash is escalating.

On Monday afternoon, Europe's Air Safety Agency decided to ground the planes on the entire continent. The move followed similar regulations in China, Australia and Brazil. According to CNN, other countries that have grounded the Boeing 737 MAX planes include China, Indonesia, and Germany among others.

There's also a number of countries that have decided to ban the whole range of Boeing's 737 MAX aircrafts, including Singapore and France.

In the U.S., however, there seems to be a different stance.

President Trump announced on Monday that he spoke with Boeing's CEO, who said "no grounding is needed."

Two U.S. carriers, Southwest and American Airlines, fly the Boeing 737 MAX 8, which includes a popular route from Boston to Miami.

Between both airlines, there are 58 Boeing 737 MAX 8 planes and as of now, neither plans on grounding them.

But the Flight Attendants Union and lawmakers are pushing for the Federal Aviation Administration (FAA) to take action.

Mass. Senator Elizabeth Warren released a statement questioning the reason these planes were pushed into service so fast.

"While we do not know the causes of these crashes, serious questions have been raised about whether these planes were pressed into service without additional pilot training in order to save money," Sen. Warren said.

In response to the growing concerns and criticism, Boeing said in a statement Tuesday on its official Twitter account that they have "full confidence in the safety of the MAX."

Understandably so, travelers are rattled. If you want to know if the flight you booked is on a MAX 8 jet, you can check online.

Passengers can look up the model of the plane they're flying on for any given flight. It's often listed on boarding passes or tickets, or you can call and ask the airline.

For American, they list the type of plane right on the schedule and for Southwest, you have to click on the flight number to see the type of aircraft.
