Terrified passengers aboard a Cathay Pacific plane prayed together as their aircraft, one of its engines on fire, made its way back to Singapore on Monday, and their calm response earned praise from the captain.

Cathay Pacific Airways Ltd said the Airbus 330, bound for Jakarta with 136 passengers on board, landed back in Singapore “without incident” just before 2 a.m. It said the crew shut down the engine after receiving a “stall warning”.

Hong Kong-based Cathay Pacific said it and engine maker Rolls Royce were investigating the incident.
