"Flying from Dubai (DXB) to Oslo (OSL), Norwegian Air’s two-month-old Boeing 737 MAX 8 encountered engine trouble, and following around 20 minutes of flying at its cruising altitude of 32,000ft…the newly built American jet initiated an emergency descent to Shiraz International Airport, located in south-central Iran.
"Before its landing, the aircraft circulated several times over the region, after flight crew closed down Engine #1 due to an ‘engine oil-associated’ fault on the brand-new jet."
