( CNN ) -- After part of an engine fell off a Qantas plane in mid-flight Thursday , a passenger shooting a personal video recorded the pilot announcing , calmly , that the flight was experiencing a `` technical issue . '' `` I do apologize , '' the pilot begins . `` I 'm sure you are aware we have a technical issue with our No . 2 engine . We have dealt with the situation . The aircraft is secure at this stage . We 're going to have to hold for sometime whilst we do lighten our load by dumping some fuel . '' The pilot then tells passengers on the Airbus A380 that there is a `` checklist we have to perform . '' `` I 'm sure you are aware we are not proceeding to Sydney at this stage , '' the pilot says . `` We 're making a left turn now to track back towards Singapore and as we progress with this we 'll keep you [ informed ] but at this stage everything is secure . [ The ] aircraft is flying safely and we 'll get back to you very shortly with further information . Thank you for your patience . '' The video is shot facing out the passenger 's window and focuses squarely , without panning , at the wing of the plane . Damage to the wing is visible in a video shot by a passenger . Volume is low , but it sounds as if conversation on the plane continued as normal , suggesting no one realized the gravity of what had happened . The cowling , or covering , on the engine reportedly fell off about 15 minutes into the flight . There were 440 passengers and 26 crew members aboard the flight which left Singapore bound for Sydney , Australia . The plane returned to Singapore . Everyone was safe . Passengers later described hearing alarming sounds while in the air . Meg Graham said she heard a loud bang within minutes of the plane departing . `` And then another bang , '' she said . Ulf Waschbusch said the crew kept passengers apprised of what was happening . `` We all stayed pretty calm , '' he said . `` It was an almost eerie calm . '' CNN iReport : 'We saw the debris ' Qantas , Australia 's national airline , has grounded its Airbus A380 fleet . Flights of the twin-deck planes -- the world 's largest airliners -- will remain suspended until an investigation into Thursday 's incident is complete , said airline CEO Alan Joyce . `` As long as it takes , '' Joyce said , responding to a reporter 's question about how the suspension would last . `` We are being very cautious until we know exactly what caused this . '' Qantas now has six A380s in its fleet of 191 planes . Airbus will at some point deliver another 14 , the airline said . One of the four engines on a Qantas airliner shut down six minutes after takeoff Thursday from Singapore 's Changi Airport , Joyce said . Part of the engine 's covering -- know as cowling -- tore off while the plane was above the western Indonesian island of Batam . `` I am not sure what actually happened with the debris and why parts of the engine left the aircraft and fell into the ground , '' Joyce said . `` We 're still looking at what exactly was the cause of that . '' Local television stations in Indonesia showed debris with red-white markings . A security officer at a Batam engineering firm said he heard a loud explosion and saw smoke coming out of the engine of a flying plane . The man 's name is Trifuadi . ( Many Indonesians go by only one name . ) He said that debris fell from the plane . Airline investigators plan to work with the plane 's manufacturer as well as Rolls-Royce , the maker of the engine . `` Safety is always our highest priority , '' a spokesman for Rolls-Royce told CNN . `` We are currently analyzing the available information and working with our customers to support their operations . '' Singapore Airlines announced Thursday that it has temporarily halted flights of its 11 Airbus A380s to do precautionary checks in light of the Qantas incident . Lufthansa , which operates three Airbus A380s , said its operations currently are `` normal . '' `` We are on standby to go further but no decisions have been taken . We are checking with Rolls-Royce and Airbus to see if they think there is a broader view , do they think we need to make special checks , '' a Lufthansa spokesman said . `` We do a lot of engine monitoring . We have a lot of information to see if there is anything abnormal and we do not have anything at the moment .
