Much of the world, including the entire European Union, grounded the Boeing jetliner involved in the Ethiopian Airlines crash or banned it from their airspace Tuesday, leaving the United States as one of the few remaining operators of the plane involved in two deadly accidents in just five months.
Britain, France and Germany took steps to keep the Boeing 737 Max 8 out of the air, joining Asian and Middle Eastern governments and carriers that also gave in to safety concerns in the aftermath of Sunday's crash, which killed all 157 people on board.
Indicating possible trouble with a reportedly damaged flight data recorder, British regulators said they based their decision on the fact that "we do not currently have sufficient information from the flight data recorder we have."
While it was business as usual at North Texas airports on Tuesday, the debate rages away from the tarmac. More countries and airlines grounded Boeing 737 Max 8.
Texas Senator Ted Cruz believes the U.S. should follow other countries’ moves, writing: “I believe it would be prudent for the United States likewise to temporarily ground 737 Max aircraft until the FAA confirms the safety of these aircraft.”
Lori Bassani is president of an American Airlines flight attendant union based in North Texas.
American flies 24 Max 8s. Southwest Airlines flies 34.
The Association of Professional Flight Attendants is now calling for American to ground the planes. The union says some of its flight attendants have already refused to get on the Max 8.
“We have a few flight attendants that are very concerned and they have expressed those concerns to their managers,” Bassani said. “Some of them will not be flying that aircraft. That's correct.”
The problem suspected in the crash of an Indonesian flight last fall centers around an automated system that causes the plane to tilt down suddenly.
Voluntary pilot safety reports reviewed by FOX 4 show U.S. airline pilots reporting similar issues at the helm of a Max 8. One wrote, “I looked at and engaged autopilot.” The pilot then saw alerts “descending” and “don’t sink don’t sink.”
The pilot later wrote “with the concerns with the Max 8 nose down stuff, we both thought it appropriate to bring it to your attention.” Another pilot reported after setting autopilot “within two to three seconds the aircraft pitched nose down.” In both cases, pilots quickly solved the problem. But some fear more needs to be known about the two crashes before getting the Max back up in the air.
“It's for an abundance of caution. We don't have any information because that determination has not been made, but that's one of the issues,” Bassani. “We want to make sure the investigation has been thoroughly accomplished, and we would like our CEO and our company to temporarily ground these planes until that does occur.”
Turkish Airlines, Oman, Norwegian Air Shuttle and South Korean airline Eastar Jet were among the latest carriers to halt use of the Boeing model. Ireland, the Netherlands, Malaysia, Australia and Singapore suspended all flights into or out of their cities.
A Turkish Airlines official said two Britain-bound planes returned to Istanbul after British airspace was closed to the aircraft. The official spoke on condition of anonymity because he was not authorized to speak publicly.
U.S.-based Boeing has said 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. Its technical team joined American, Israeli, Kenyan and other aviation experts in the investigation led by Ethiopian authorities.
The Federal Aviation Administration said it expects Boeing will soon complete improvements to an automated anti-stall system suspected of contributing to the deadly crash of another new Boeing 737 Max 8 in October.
Some U.S. airlines expressed support for the Boeing model, and American Airlines and Southwest continued flying them. A vice president for American, the world's biggest carrier, which has 24 Max 8s, said they had "full confidence in the aircraft."
Safety experts cautioned against drawing too many comparisons too soon with the Lion Air crash in Indonesia in October that killed 189 people.
But others in the U.S. began pressing for action.
The Association of Professional Flight Attendants, which represents more than 26,000 flight attendants at American Airlines, called on CEO Doug Parker to "strongly consider grounding these planes until an investigation can be performed."
Consumer Reports called on airlines and the FAA to ground the jets until a thorough safety investigation is complete.
Even President Donald Trump weighed in, tweeting that additional "complexity creates danger" in modern aircraft and hinders pilots from making "split second decisions" to ensure passengers' safety.
He did not specifically mention the crashes but said, "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, killing people from 35 countries.
A pilot who saw the crash site minutes after the disaster told the AP that the plane appeared to have "slid directly into the ground." Capt. Solomon Gizaw was among the first people dispatched to find the plane. The wreckage was discovered by Ethiopia's air force.
"There was nothing to see," he said. "It looked like the earth had swallowed the aircraft. ... We were surprised!" He said it explained why rescue officials quickly sent bulldozers to begin digging out large pieces of debris.
Ethiopian Airlines, widely seen as Africa's best-managed airline, grounded its remaining four 737 Max 8s until further notice. The carrier had been using five of the planes and was awaiting delivery of 25 more.
On Tuesday a group of officials from China, which also grounded planes, paused in their work at the scene to reflect with an offering of incense, fruit, bread rolls and a plastic container of the Ethiopian flatbread injera.
As the global team searched for answers, a woman stood near the crash site, wailing. Kebebew Legess said she was the mother of a young Ethiopian Airlines crew member among the dead.
"She would have been 25 years old but God would not allow her," she wept. "My daughter, my little one."
As night fell, Ethiopian Airlines offered no new updates on the investigation. An airline spokesman said victims' remains should be identified in about five days.
Some insights into the disaster and its cause could take months, aviation experts said.
"The conclusions that will come out of its probe will be beneficial to the rest of the world," Ethiopian Prime Minister Abiy Ahmed said Tuesday at a news conference with visiting French President Emmanuel Macron. "These types of accidents break everyone's heart. I hope we will learn from this crash."
