This is the story of United airlines flight 1175 , on the 13th of february 2018 a huge boeing 777 was to take off from san francisco international airport to hawaiis honolulu international airport. The jet was packed with 378 people on board. The plane took off from sanfrancisco with no issues and it made its way across the pacific ocean with no issues. As the plane was getting near to hawaii the everyone onboard was getting ready for the landing, they were still at 36000 feet and hadn not begun their descent yet. at noon hawaiian time flight ___ was about 40 minutes from landing and that is when the plane was rocked by a huge explosion. The flight crew heard a loud bang and then the plane started shaking. Their EICAS displays lit up with warnings of a compressor stall on engine number right hand engine or engine number two. The bang had disconnected the autopilot and the plane started to yaw to the right. The captain immediately called my controls and took control of the plane righting the plane while he tried to figure out what was happening to his jet. They kept getting an intermittent waring on their consoles about the right hand engine failing. Something catastrophic had happened to the right hand engine and the pilots werent taking any chances, the captain called for the severe engine damage checklist and the first officer started going through the checklist while the captain focused his attention on keeping the massive plane in the sky. Once the engine was shut down the pilots could feel that the vibrations had gone down but they knew that the controllability of the plane was not normal. Now that they had a good handle on the situation the pilots control on the situation the pilots briefed the controllers about what was happening to them and declared an emergency. The captain sent the person the jumpseat into the cabin so that they could have a good idea of what was happening with the right hand engine, the jump seater did not have good news for the captain, he took a video of the engine and showed it to the captain and it showed the engine just swinging from side to side with most of its cowlings missing. I mean this engine was destroyed, the bang that everyone had heard on board now made sense. For whatever reason the right hand engine of the 777 had failed and catastrophically at that. The pilots now needed to get this plane on the ground as soon as possible and their destination of honolulu was indeed the closest airport to them. Since the flight was almost over the pilots did not have to worry about weight being an issue or else they would have to dump some fuel overboard and believe me sometimes that can be an issue. With that the pilots carefully lined the jet up with runway 8R at honolulu, the pilots would be carrying out a visual approach for this landing and soon after that flight 1175 made a safe landing. The interesting thing is that just mere decades ago the 777 or a plane like that would not have been able to make this crossing. You see back in the day the FAA banned planes with fewer than three engines from flying over large bodies of water because jet engines were new and they failed a lot, so the wisdom was that the more number engines you have the better your chances of losing a few engines and making it back alive. And they really loved this rule for example. In 1980 the FAA administrator Lynn helms said this and i quote “It'll be a cold day in hell before I let twins fly long-haul over-water routes”. But just two years later hell started to thaw as the FAA started seriously studying the possibility of letting twins fly long distances over water. Then they relented and let twin engines planes fly over water, but not without any restrictions though, you see each plane had an ETOPS rating, or Extended-range Twin-engine Operational Performance Standards or more colloquially known as engines turn or passengers swim. Its basically the amount of time a plane can fly from a diversion airport. In case of the 777-200 that united was flying that day it has an etops rating of 180 minutes or in other words at all points in its journey it has to be utmost 180 minutes away from a diversion airport so that if something does go wrong with one engine the plane can reach the emergency airport on one engine.
In the case of flight 1175 all that etops preparation came to gether perfectly to get this damage plane back on the ground in one piece, well not one piece but you know what i am saying. Once on the ground they could finally see the extent of the dama
