Woman survives in car for nearly 1 week after crashing into creek in Northwest Indiana: sheriff
Cassell fell asleep behind the wheel before crashing in Brook.

"She had fell asleep and veered off the road and went into a very big, deep ditch. It couldn't be seen from the road," said Delmar Caldwell, Cassell's father.

Resilience and a simple piece of clothing helped Cassell to survive nearly six days while injured and trapped in her crashed car. Her phone lost power, and the 41-year-old was unable to move.

12 people with minor injuries after American Airlines plane catches fire at Denver airport
DENVER (AP) — Twelve people were taken to hospitals after an American Airlines plane landed at Denver International Airport on Thursday and caught fire, prompting slides to be deployed so passengers could evacuate quickly.

All of the people transported to hospitals had minor injuries, according to a post on the social platform X by Denver International Airport.

Flight 1006, which was headed from the Colorado Springs Airport to Dallas Fort Worth, diverted to Denver and landed safely around 5:15 p.m. after the crew reported engine vibrations, the Federal Aviation Administration said in a statement.

While taxiing to the gate, an engine on the Boeing 737-800 caught fire, the FAA added.

Photos and videos posted by news outlets showed passengers standing on a plane’s wing as smoke surrounded the aircraft.

You would hope that the engine had been shut down, which would make the cause of the fire even more of a puzzle.

Just curious... I thought there are no inflatable slides at wings of B737 because they are just ~1.5m above ground, so passengers evacuating via overwing emergency exits are required to go down the extended flaps resp. the wing's trailing edge.

No real surprise about the fire - it had probably started before the plane stopped.

But why?
Significant engine problem- shut it down.
With the engine shut down before even landing, there shouldn't be enough residual heat to start a fire once down & stopped. Even so- if there is a fire- there should be a fire alarm, aircrew discharge fire bottles. But there have been no reports of a fire prior to the aircraft coming to a stop.
Yet another puzzling incident.

Apparently once the engines have been shut down, using the battery power to extend the flaps takes ages.

I meant it this way: people fear climbing off the trailing wing edge of a 737 (which has short landing gear for low ground clearance) more than the plane eventually bursting in flames? That seems irrational.

Blancolirio has just posted his video about this:
https://www.youtube.com/watch?v=Q9zzt9bNKQ8

Point to note - the aircraft had arrived at the gate before the fire broke out, there is some indication that there was a fuel leak in the area of the engine/undercarriage, both of which are screaming hot, so could easily set fuel ablaze. Also with the flaps up there appears to be a good few feet drop to ground... Did the crew start the evacuation, or did passengers - that's a big question.

This series of 737 the wing is higher above the ground than on the older series- about 12ft or so i think it is. Quite a drop.
And as it was, the fire was on the other side of the aircraft and not fully involved.

Certainly the case if it hadn't been shut down prior to arriving at the gate.
But the reason for the diversion was due to engine vibration issues, so even if it was left at flight idle till landing, then leaving at idle until arriving at the gate just seems odd to me. I guess it depends on what the checklist said to do.


Edit- from the video, sounds as though reducing power stopped the vibrations, so the engine was left running as per the quick ceck list.
So, yeah- plenty of heat to start a fire (not just with fuel but also enough heat for oil/hydraulic fluid to ignite as well).

I sense a pile of assumptions in the posts here. Assumptions about how systems are connected.

First the fuel pump isn't just engine driven kind most think of. It is electric and runs even if the engine is at a dead stop. Second the engine is lower than the tank of the wing so gravity feed happens. Third even with the fuel valve closed oil and hydraulic fluids are under pressure is the engine core is turning. Four the main gear brakes are glowing red after a landing, a nice ignition source. Five hydraulic lines may be pressurized from the other engine. Six hot bleed air from the other engine or APU may be there. Seven Electric spark is also a possible source.

Now a remember, you can't use reverse thrust on one side only, so the plane has to stop on brakes only making them extra hot.

Now I'm going to guess that a flammable fluid line cracked from the vibration and it wasn't until the aircraft slowed that it made a big enough puddle for something to ignite it.

Yeah, but you'd hope that part of shutting the engine down would also be shutting down the pump for that engine (or is it a single pump for both, with a second redundant pump & the pumps selectable (along with the tanks))?

Excellent points (that i managed to completely overlook...).

On landing, and take off, the electrical fuel pumps are switched on to keep up the pressure if the mechanical pumps fail.

On March 24 2015 Germanwings 9525 an Airbus A320 en route from Barcelone, Spain to Dusseldorf, Germany crashed into a rocky massif near Barcelonnette, France. The cause was quickly announced by French authorities just 49 hours after the crash. The co-pilot committed 'suicide' (that is: mass murder) and steered the aircraft into terrain. The air accident investigation came to the same conclusion, years later.

Now, in a bombshell report the Austrian Simon Hradecky, founder and operator of the air accident bulletin "The Aviation Herald" who is highly respected among commercial airline pilots, has apparently done everything in his power within the past eight years to thoroughly reexamine this mysterious accident. He obtained copies of all investigation files from the French and German investigative authorities (21,000 pages). He recreated the incident in own experiments for which he bought original certified Airbus hardware and was able to demonstrate a technical malfunction in the autopilot's altitude selection. He repeated this demonstration in a real flight simulator with a A320 certified training captain, a malfunction which had previously been ruled out.

He was led to this conclusion by a series of false facts, wrong assumptions and erroneous conclusions in the official investigations, which, for him, created the impression that from the start the investigation solely aimed at evidence for the predetermined cause of "suicide." Example: it wasn't an air accident board who conducted the investigations but just a Marseille investigative court and a German states attorney; not France' BEA or Germany's BFU, no psychologists, or human factor experts. No relatives or colleagues ever identified the different voices on CVR recordings. Just (supposedly wrong) assumptions. Strange.

The predetermined cause "suicide", Hradecky argued, can be ruled out with certainty; a technical malfunction together with a supposed medical emergency (captain, not the copilot) caused the crash. The authorities possess necessary evidence for this conclusion from CVR, FDR, and victim traces recorded (photos, ID numbers, reports) at the accident scene.

Hradecky has summarized his findings in a detailed report for ICAO and EASA, verified by active and retired air accident investigators from other countries. It will be published in a book in August (to cover his extensive expenses).

This Hradecky is a serious guy; renowed for 17 years of his 'just facts, no rumours' stance in his Aviation Herald reports.

Before, he frequently admonished French, Spanish, Russian air accident authorities for not adhering to English language as required by ICAO; but never in 17 years he was scrutinizing an official air accident report; not a 'Central African one'[*], even less so a French or German one.

[*] Please excuse my patronizing prejudice for the sake of an example.

The reactions to this report are largely negative: Confirmation bias. Loss of neutrality. Conspiracy theory. Loss of reputation...

The author defends each of his claim with facts. Nevertheless, he's not in charge to formulate such far-reaching claims; years of meticulous obsession with this accident may have influenced his professional distance from the event.

Just look at how the thrown gauntlet is now being received by French and German authorities. A book publication, ~700 pages... A bold (overconfident?) move. A SkyTV documentary...

It doesn't change the fact that the co-pilot had certain mental issues and was under the influence of medication.

The formerly unbiased Aviation Herald here takes a side against French authorities: The official investigation was flawed from the start, the cause of accident misidentified.

There's not a lot that you can do when the road suddenly falls out from underneath you.

Horror moment giant sinkhole swallows biker who plunges to his death.

This is the shocking moment a motorcyclist fell to his death after a giant sinkhole unexpectedly opened up before him in the middle of a Seoul street.

The 33-year-old man, identified by his surname Park, was found dead before noon on Tuesday after 17 hours of overnight search efforts.

Harrowing dashcam footage from a vehicle travelling behind him shows the biker plunging right into the sinkhole......

Now back to things that fall out of the sky.

Horror moment air force jets collide in mid-air.

Two French air force jets have been captured colliding mid-air while rehearsing a stunt.

The crash occurred in Saint-Dizier, eastern France, yesterday afternoon during a drill involving six Alpha Jets.

Terrifying footage shows a group of jets flying in an organised line and firing coloured smoke flares when two planes suddenly collide mid-air.

They quickly begin to plummet and disintegrate on impact as debris falls from the sky.

Authorities have since confirmed that both aircraft were destroyed in the crash.

The shocking footage shows three pilots quickly ejecting as fireballs erupt below them......
