( CNN ) -- Panicking passengers turned to prayer as a Cathay Pacific flight with one engine ablaze made an emergency landing in Singapore on Monday , witnesses said . `` We heard a series of loud bangs , then smelled fire , and the aircraft started shaking uncontrollably , '' a CNN.com online commenter under the name of Augustus2002 said . `` The noise on board was incredible , we could not hear any of the announcements of the crew , '' he added . CNN has not been able to confirm his account , but it matches a description from a Reuters photographer who was on the plane with his family . The photographer , Beawiharta , who uses only one name , told the news agency that his 15-year-old son spotted flames out the window of the twin-engine Airbus A330 , which was on the way to Jakarta , Indonesia , but turned back after the engine problems began . `` Panicked , he then asked : 'Will we die ? Will we die ? ' `` the photographer recalled . The atmosphere among the plane 's 136 passengers quickly changed to a `` surprising calm , '' Augustus2002 wrote , as people began to pray . `` God , save our flight , '' they said , according to Beawiharta 's account . `` Give us your protection . '' Flight CX715 landed safely , the airline said in a statement `` following a stall warning '' on one engine . No passengers were injured . The flight landed at Singapore Changi Airport , where it had originated . `` Fire services met the aircraft on arrival , '' Cathay Pacific 's statement said . `` The aircraft stopped on the taxiway and sparks from the No . 2 engine were reported . They were doused by fire extinguishers . '' Cathay Pacific and Rolls Royce , the maker of the engine , have launched an investigation into the incident , which has been reported to the Hong Kong Civil Aviation Department , the airline said . `` We are aware of the incident and working closely with our customers to provide support and technical assitance , '' Rolls Royce said in a statement . It was the second time one of the Hong Kong-based airline 's Airbus A330 planes has made an emergency landing . Eight passengers aboard a Cathay Pacific plane were injured last year after an Airbus A330 with engine problems made an emergency landing in Hong Kong . Several tires deflated as the aircraft landed at high speed with severe braking , the company 's CEO said at that time . Less than a month later , an Airbus A330 plane operated by Afriquayah Airways crashed just before landing in Tripoli , Libya , killing all but one of the 104 passengers on board . Shortly afterward , investigators said low visibility caused by mist and sand created poor flying conditions for the plane 's pilot . CNN 's Ayesha Durgahee and Andrew Henstock contributed to this report .
