Travelers react as Boeing 737 MAX faces intense scrutiny following 2 crashes

PHOENIX (FOX 10/AP) -- The Ethiopian Airlines crash over the weekend has resulted in intense scrutiny for the plane model involved in the crash.

Air safety regulators in at least 40 countries, including the European Union, have either grounded Boeing 737 MAX jets or banned them from their airspace after Sunday's deadly crash in Ethiopia. In addition, at least 10 airlines worldwide have stopped flying the planes.

The European Union Aviation Safety Agency, which covers 32 countries, announced Tuesday that it would ban the planes from flying in its airspace. Other countries that have either grounded the planes or temporarily banned them include China, the United Kingdom, India, Indonesia, Singapore, Oman, Malaysia and Australia.

Airlines that have stopped using the planes include Gol Airlines of Brazil, Cayman Airways, Ethiopian Airways, Jet Airways of India, Aeromexico, Norwegian Air Shuttle, Turkish Airlines, Eastar Jet of South Korea, Smartwings of the Czech Republic and LOT of Poland.

Meanwhile, The U.S. Federal Aviation Administration is facing mounting criticism for backing the airworthiness of the jets.

At Sky Harbor, travelers were reluctant to talk about the woes the jet model is facing, but they'd rather be safe than sorry. FOX 10's Matt Rodewald reports.
