Commercial jet left Denver, started losing parts and returned to Denver.

Large parts in Broomfield residential area.

2. Damn! Boeing again.

[mobeau69]

8. If that's correct it'll crush them.

[Sanity Claws]

17. My guess is that it's a mechanics' problem

Probably using non-union mechanics to save money at the expense of safety.

[mobeau69]

18. That's my guess too. Fasteners missing or not tightened to specs.

[The Velveteen Ocelot]

27. Not Boeing - the engine manufacturer is Pratt & Whitney.

Could be a manufacturing defect (P&W's problem) or a maintenance issue (United's problem), but not likely to be Boeing's problem.

[notinkansas]

30. That makes sense.

Do I have to apologize to Boeing now?

[DeminPennswoods]

39. Likely a compressor disk or compressor blade failure

Forgings from which disks and blades are made sometimes have irregularities that produce parts that can fail under the right conditions. Sometimes it's impossible to identify parts prone to fail until one actually does, then you can do either regular inspections or replace the part after x many hours regardless. Sometimes a part will give a warning it might fail by developing a tiny crack first, but sometimes they pass inspection and fail without any warning at all even with the best regular maintenance and compliance with tech directives.

40. That's what happened years ago with United 232 at SUX.

And the uncontained failure sent pieces through the vertical stabilizer and cut a hydraulic line.

[DeminPennswoods]

43. USN lost an F14 years ago

from an uncontained fan blade failure for the same reason, cut hydraulic line.

12. If it falls in my yard do I get to keep it?

That would make an awesome lawn ornament.

[Mariana]

16. I thought the same thing. nt.

[The Velveteen Ocelot]

31. The NTSB will take it away, unfortunately.

[hunter]

33. Life's not fair...

[gldstwmn]

41. It totaled his truck.

Somehow I don't think he's too fond of it.

25. holy crap.

[PSPS]

29. OMG! That's Shatner-esque plus it's real!

[LeftInTX]

38. Not nice, but...

[mobeau69]

3. Looks like a finishing ring of sorts for an engine.

[Karadeniz]

4. Those poor passengers! Someone's going to catch hell for this.

[LisaM]

5. Those poor neighborhood residents!

Can you imagine the nightmares they'll hav

[Karadeniz]

19. Yes!! Their terror lasted a minute, but the passengers spent the entire flight back wondering each

Second if it was their last. Flying to Japan in 1954, the kitchen caught fire. I slept through it!

[LisaM]

37. But every time a plane goes over their house..

They will flinch.

[dchill]

6. And bound for Honolulu, no less!

Good thing it didn't hold together for, say, half the flight!

[Ohiogal]

7. Thank goodness it missed that house and no one was hurt.

[hlthe2b]

9. I hate hearing this at all. I hate hearing it about any airline. I hate hearing it about United

especially, given that is what I usually fly.

Yikes. Glad everyone is ok.

Enroute to Honolulu--I'm reminded of this (Aloha Airlines, 1988)

[mobeau69]

13. That was truly unbelievable!

[hunter]

20. My brother saw that.

It made him anxious about flying for a long time.

I've always been anxious about flying.

[frogmarch]

42. A female flight attendant was sucked out and her

body was never found. Lots of injuries to passengers, some serious.

It is amazing that no one on the Colorado flight today, or anyone on the ground, was injured or killed

[sanatanadharma]

10. Big "Q" fell out of the sky

It's little dingie is buried in the earth.
A sign from the heavens that Bettie Qrocker is cooking up just desserts.

Seriously, WTF?

36. Weird. Denver to Denver flight.

All as if normal!

[sarcasmo]

14. Watch out for the friendly skies.

[Backseat Driver]

15. Whoa - looks like a close call on that home...

Long time since, early '70s, on an October flight from LA to Honolulu our jet lost A/C over the ocean half way there - we were instructed to close the blinds - all the ice onboard melted and the soda got warm - it was as hot as a Vegas street at noon in the cabin by the time we safely landed - Not one "hospitality" deal was offered for our suffering.

[Yavin4]

23. Since covid has depressed airline travel, are the airlines skimping on maintenance? n/t

Flight 328 @united engine caught fire. my parents are on this flight 🙃🙃 everyone’s okay though!

[Vinca]

26. Terrifying. Lucky for them it didn't happen in the middle of the Pacific.

[FBaggins]

34. The 777 can fly quite a distance on one engine

Not quite the entire distance... but there isn't anywhere on the route where they would be too far from an airport to land.

The FAA won't allow a plane to fly that long a route unless it's certified for single-engine flight long enough to get back to land.

[The Velveteen Ocelot]

35. They'd have been fine. Airplanes can fly a long distance on one engine

and they wouldn't even be dispatched on an overwater flight if they couldn't make it to their destination or an alternate airport on one engine. If an engine fails at cruise altitude the plane will have to descend to a lower altitude, which means it will burn more fuel, so the alternate airport has to be within a specified distance. But all of this is calculated before the flight is dispatched. A B747 once lost 3 of 4 engines when it flew through volcanic ash and it was still able to keep flying and make it to an airport safely.

[The Velveteen Ocelot]

28. Pilots are trained for engine failures.

It's serious, obviously, but almost every training event in a simulator has an engine failure as part of the program, and there are specific procedures that are almost automatic. An engine failure at altitude is much less worrisome than one right after takeoff. In this case it looks like they lost the whole cowling but apparently there were no loose parts that hit the fuselage. Airplanes can keep flying on one engine.
