PHILADELPHIA — A Southwest Airlines jet apparently blew an engine at about 30,000 feet and got hit by shrapnel that smashed a window and damaged the fuselage Tuesday, killing a passenger and injuring seven others, authorities said.
The plane, a twin-engine Boeing 737 bound from New York to Dallas with 149 people aboard, made an emergency landing in Philadelphia just before noon as passengers breathing through oxygen masks that dropped from the ceiling said their prayers and braced for impact.
"I just remember holding my husband's hand, and we just prayed and prayed and prayed," said passenger Amanda Bourman, of New York. "And the thoughts that were going through my head of course were about my daughters, just wanting to see them again and give them a big hug so they wouldn't grow up without parents."

Southwest’s first fatality!

Looks like a 1st stage fan failure. Wonder if they had a bird strike? however, never seen one this bad before, where the entire hub, shaft and containment case are destroyed.
From the 2005 manual with specs, says the A380 AirBus carries 320,000 litres of fuel or about 160,000 liters per wing. So where does all that fuel go? I don't understand. These jet engines need that much fuel for an eight hour trip, as it says in the spec sheets.
I screenshot'ed it but look at the book specs at 3:21 minutes
From the comments on these A380 AirBus Specs for the wings and fuel distribution:
"18 tonnes of Jet fuel at 0.785 kg/l requires 150 cubic metres. With the A380 wing area at 845 square metres (Wikipedia), that's 422.5 sq m per side.
Estimating (from the fuel tank picture in your manual) the 'wet' part of each wing comprises about 60% of total area or about 250 sq m. Placing 150 cubic metres over this requires an average wing thickness of only 0.6m to store the lot.
The wing looks at least 2 metres thick at the root and one metre thick at mid span so there's plenty of space for 118 tonnes of fuel per side. Please do pick up a calculator and follow this through if in doubt. Failing that, sniff the kerosene fumes!"
and another commenter:
"He makes a strong argument about the physics of the wings being completely off the physics chart. I looked into it. 6.8 pounds
JP-5 is a complex mixture of hydrocarbons, containing alkanes, naphthenes, and aromatic hydrocarbons that weighs 6.8 pounds per U.S. gallon (0.81 kg/l) and has a high flash point (min. 60 °C or 140 °F).
Max. fuel capacity 323,545 L / 85,471 USgal[36
That’s 578,000 pounds loaded in the wings.
Maximum take off weight 575 t (1,268,000 lb)
So half of his weight is in the wings. 😜😂🤣"
Thank you for taking the time to reply...!
Photo didn’t post?
On the news, it said the very same accident has happened on this airline before, but with no casualties. So as a Freeper suggest, if you travel this airline, DON’T sit by the engine.
Ditto that post..............
I saw some incredible failures while working as a mechanic for PWA’s Experimental Division in East Hartford, CT - back in the early to mid 80’s

Fresh link: A380 Airbus carries 320,000 litres of fuel, half that in each wing
Hmm - looking at this blow-up photo - I’m trying to understand how the cowling and inlet came apart - if the fan is still intact. At first i thought it was a 2-satge fan, but then there would not be a honeycomb case for containment (usually steel with a Kevlar outer shell.
Just look for the Union label?
Horrifying.
It’s been my professional experience that the Chinese are the most unethical, amoral a-holes on the planet - almost w/o exception.
I had to look it up, but there are about 7,000 lbs of fuel in each wing in a 737. There is more fuel in fuselage tanks.
Modern planes use a high bypass turbofan engine, so the big bulky part of the engine you see at the front contains the fan (propeller!) which is connected by a shaft to a turbine aft of where the fuel is burned.
The hot gasses hit the turbine in the back, causing it to turn, and the turbine turns the fan (connected to the turbine by that shaft) generating thrust like a...well, propeller driven plane. A smaller portion of the hot gas gets expelled out the back, and that adds to the thrust.
Roughly 50-70% of the thrust from a high bypass turbofan engine comes from the fan blades, and the remainder from the core exhaust.
Each engine overall generates about 20,000 lbs of thrust.
One fan or compressor blade becoming unbalanced for any reason, or foreign body damage to a blade causing a harmonic vibration and domino effect on other blades, or over RPM. So many things, their mechanics will know with just a cursory look and data recorder. The pilots did a helluva job setting it down
Excerpt from below link
There are only two solid rules regarding jet engines; The airflow through the engine can never exceed the speed of sound and the maximum RPM isn't far from the point where the engine starts slinging compressor blades.

LOL, let me tell you, I had kidney stones for several months, and it made my bladder so unpredictable and weak that there were times I would have gone into a bathroom if there were turds on the deck.
The plane was at about 38,000 ft when the engine broke apart. I think that is too high for a drone.
Ugh. That’s terrible. MD-80 was a good plane, as I recall. I flew on many of them back in the day!
Hmmmmmm. I gather your commercial aviation crash reference has expunged the demise of Obama Birth Certificate production Director Loretta Fuddy’s on 12/11/13 as a consequence of a plane “ditched onto open ocean waters” (which was a lie), whose engine was claimed to have had a catastrophic failure (about which the NTSB also lied).
...
That flight was classified as an air taxi/commuter, not an air carrier.
The engine was not properly maintained. Several people outside the NTSB would have been involved in a conspiracy in order for the NTSB to get away with a lie.
Your claim is rejected.
100% agree.
