Dear friends and followers, welcome back to my channel!
On the 20th of February 2021, a United Boeing 777-200, registration N772UA performing flight UA-328 from Denver,CO to Honolulu,HI (USA) with 231 passengers and 10 crew, was in the initial climb out of Denver's runway 25 when the right hand engine's (PW4077) inlet separated associated with the failure of the engine. The crew declared Mayday reporting an engine failure. The aircraft stopped the climb at about 13000 feet, the crew requested to return to Denver after running the checklists. ATC offered any runway, they would make it happen. The aircraft returned to Denver for a safe landing on runway 26 about 23 minutes after departure. The aircraft stopped on the runway for a check by emergency services. Emergency services advised of an active fire within the right hand engine and extinguished the fire a few minutes later. The aircraft was subsequently towed off the runway to a remote parking stand, where passengers disembarked and were bussed to the terminal. There were no injuries.
The engine inlet fell into the neighbourhood of Broomfield,CO, located about 16nm west of Denver near 13th and Elmwood Street, the debris also struck through the roof of an adjacent house.
Broomfield police reported that although debris impacted the neighbourhood and damaged a number of homes, there were no injuries on the ground. The debris field expands over a nautical mile.
Ground observers reported hearing the sound of an explosion like bang, smoke and saw the debris falling down. The aircraft continued flying.
Watch the video to learn more about what happened!
Thank you very much for your time! I hope you enjoy this video!
Wishing you all the best!
Your "Captain" Joe

    For those of you making jokes of this situation that happened in real life. Stop for a moment and think if you were their and then here what this guy has to say about what the pilots need to do in order to control the situation and not make it worse. Some of you people hate the fact that other people where saying that they got lucky, which is true. They got lucky that they where in Good Hands and Gods Hands, and J.P. Quixote Seems to be playing God. So do what's right and that guy seems to have 44 likes so please, Report his comment and do what's right. FYI the pieces that fell of could of got caught on the ruder of the plane so they are lucky it landed safely in someones yard. It also may seem like it's shaking in control, but he said in the video that it's shaking even more because something is missing. Just watch it with an opened mind :)

    It's BRoomfield with an "R", not BLoomfield... 😉 (Named after the broom handle corn that used to grow here..) It was definitely a very loud boom. I heard it from inside my house and thought it sounded like a sonic boom. I initially thought that someone might be getting in trouble for that. (I'm actually old enough to remember hearing those as a kid...) We do have a fairly large non-commercial airport close to us, that occasionally runs military jets out of it, along with small and large corporate jets, and firefighting aircraft. (Rocky Mountain Metropolitan Airport)

    they had control & did right thing & landed safely yeah, but if they didn't hve control say bad fire problem. They could turn super hard tight left turns to help get fire out & burn off extra wt & get to ideal lower thicker air so they hve more control at slower speeds,. Making 3,4,5,6 tight turn toward denver than landing might hve been safer allowing time to fully assess damage & flying ability & time to dump fuel b4 landing light & near empty like a paper airplane.

    Very good and useful summation given how long we must wait for NTSB. Couldn’t help noticing that your graphic of the fire drill ended up with the second bottle arrow pointing at no. 1 engine! That emphasizes how critical it is to confirm every shutdown move on a twin. Be careful of condescending language re “boys and girls”. Great job and thanks. Long retired 747 Captain.

    I live in Broomfield. I was sitting in my apartment watching youtube when this happened. When I heard the big boom I thought for sure it was a fighter jet that had broken the sound barrier or something (there are always fighter jets coming in and out of the Broomfield airport) I looked out my window and saw this passenger plane way up in the sky and was like huh that was weird....only later did I find out that airplane parts were falling out of the sky near me. Pretty awesome that these planes can have an engine explode and still be able to fly

    Captain Joe. Some years ago I was flying out of Denver in an Airbus. We were told the they lost hydraulic control and were flying the airplane with engines controlling rise and climb, and left and right turns. The ailerons weren't working nor were the flaps. We ended up circling back to Denver in the scariest flight I've ever been on. And with no flaps the landing was extremely fast using up all of the longest runway they had. Maybe you can go back and find that one or one similar and break it down. I will say it was around 2005-2007.

    A few corrections to your commentary: 1) This does NOT appear to be an "uncontained" event. Here, the engine case / containment shroud was not breached. The cowl ring isn't part of that. For a great explanation of this: ar-state.com/v/hoLcl9WomZidndI/fydyw.html 2) Initial checklist run would have been Eng Severe Damage/Separation which applies with airframe vibration + abnormal eng indications present. *None of this checklist is memory* - engine shutdown is always done via checklist and very tight crew coordination. 3) Turns into the dead engine in the B777 are not a consideration. There's plenty of rudder authority for turns either direction as long as airspeed remains above min maneuvering speed. In this case, the jet was accelerating out of 250 toward climb speed which typically is 300-320 KIAS. 4) The left turn was made due to terrain considerations. And FYI: I have almost 12000 hours in type and have flown this tail number numerous times. The B777 is an absolutely fantastic aircraft. The crew here did a great job - what we're trained for and exactly what we brief on each and every flight.

    Single pilot is right around the corner Joe... In my lifetime I remember hearing, "We MUST have that third man in the cockpit to reduce our workload", to, "well, we can do it with two thanks to automation"... Automation will spell the end of the 1st officer!!! And, I believe in my lifetime we'll see the end of captain's as well... You're just system managers now for goodness sakes!!! The ONLY time you actually fly the plane is take offs and landings... And these new planes don't need you for that either!!! Sorry sir, but you've become irrelevant!!! I'm NOT in favor of this... But it's coming... SOON!!! (And I am a private pilot, so I get your argument)
