Aviation regulators worldwide laid down a stark challenge for Boeing to prove that its grounded 737 Max jets are safe to fly amid suspicions that faulty software might have contributed to two crashes that killed 346 people in less than six months. The Max jets are likely to be idle for weeks while Boeing tries to assure regulators around the world that the planes are safe. Some industry officials think the plane maker and U.S. regulators may be forced to answer questions about the plane's design. The Max is the latest upgrade to the Boeing 737, which has been flying since the late 1960s. The airline, which has 34 of the 72 U.S.-based Max planes that were in operation, canceled 39 flights Thursday due to the grounding.
