A plane carrying 62 passengers and five crew members has crashed during an emergency landing.

An Azerbaijan Airlines passenger jet has crashed during an emergency landing near Aktau in south-west Kazakhstan.

There were reportedly 69 people aboard. Kazakh authorities said 38 people were killed in the crash, while the remainder survived.

The jet was flying from the Azerbaijan capital of Baku to Grozny in Chechnya, Russia when it crashed, the Kazakh transport ministry said on Wednesday.

“A plane doing the Baku-Grozny route crashed near the city of Aktau. It belongs to Azerbaijan Airlines,” the ministry said on Telegram.

Azerbaijan Airlines, the country’s flag carrier, said the Embraer 190, designated Flight J28243, had “made an emergency landing” around three kilometres from Aktau, an oil and gas hub on the eastern shore of the Caspian Sea.......

Another of PooTin's rust buckets becomes an environmental hazard.

Russian cargo ship sinks in Mediterranean Sea after engine room explosion.

A Russian cargo ship has sunk in the Mediterranean Sea between Spain and Algeria, leaving two crew members missing, according to Spain's maritime rescue agency and the Russian Ministry of Foreign Affairs.

The Spanish agency said on Tuesday local time that 14 crew members of the Ursa Major vessel had been rescued uninjured and transferred to the Spanish port of Cartagena. The remaining two crew members are still missing.

Russia's foreign ministry said the ship started sinking after an explosion in its engine room.

Unverified video footage of the ship heavily leaning towards its starboard side with its bow much lower in the water than usual was filmed on Monday by a passing ship and published on Russia's life.ru news outlet on Tuesday.......

And then there's those bridges that just collapse.

Chemical spill concerns after deadly bridge collapse in Brazil.

Brazilian authorities are assessing the risks of water contamination after trucks carrying sulphuric acid and agricultural pesticides plunged into a river in a deadly bridge collapse.

The central span of the 533-metre bridge, which links the cities of Estreito in Maranhão and Aguiarnopolis in Tocantins, gave way as vehicles were crossing above the Tocantins River on Sunday.

A video showed Aguiarnopolis city councilman Elias Junior making a recording asking authorities to fix problems with the bridge, which he said could no longer handle the heavy trucks passing over it.

As he pointed to a large crack on the shoulder of the bridge, a portion of the structure started collapsing in front of him, with some motorists managing to stop their vehicles in time.

A large truck was also seen on the bridge in the video before the camera turned to follow Mr Junior running towards the river.

The Maranhão and Tocantins authorities have confirmed four people have died and more than 10 people are still missing.

Rescue divers halted their efforts after finding that trucks transporting sulphuric acid had plunged into the river.......

Looking at the video, and the flight data showing altitude & air speed, it looks like they lost the use of their elevators- the plane was doing Phugoid Oscillations (aircraft would gradually climb until the air speed dropped off so much that lift was lost (stall), the nose would pitch down, aircraft descend, and as the air speed increased the lift would increase, the nose would pitch up, the aircraft would climb until it stalled, and so on). Mostly level flight can only be done by manipulating the throttle(s).
Landing without significant damage is pretty much impossible- the most famous example of what can be done was UA Flight 232 at Sioux CIty, July 1989. 296 occupants, 184 survived only due to the amazing efforts of the flight crew.

The cause of a fiery horror plane crash that killed 179 people in South Korea has been revealed.

The likely cause of a deadly South Korean plane crash that killed 179 people has been revealed.

According to airport authorities, the Jeju Air Boeing 737-800, carrying six crew and 175 passengers, likely experienced a bird strike which caused its landing gear to malfunction, Korean outlet Yonhap News Agency reported. Two flight attendants survived.

The South Korean plane was warned about birds being in the area and told to change landing runways to avoid a bird strike.

Just a minute later, the pilot made a mayday call to the control tower, according to the Land Ministry.

The aircraft then attempted a crash landing, however it failed to reduce speed and veered off the runway, smashed into a concrete wall and then caught on fire, killing most on board.

Emergency services have pulled two people alive from the wreckage — but everyone else died in the tragic incident......
But there are a few questions that still need to be answered.

Experts baffled by detail in South Korean plane crash that killed 179.

I'd say lots of questions.
Landing with the loss of one engine shouldn't be a problem.
If hydraulic pressure had been lost, the undercarriage can be released and will lock into place by gravity.

And why were the antenna for the localizer mounted on a massive prestressed concrete block. It was that, that the plane hit, not the relatively flimsy block wall.

Message 2144614 - Posted: 30 Dec 2024, 0:23:11 UTC - in response to Message 2144612.  

After seeing 3 pilot videos on the sequence, I'd say the reason for the crash is panic. They did not take enough time to go through the check lists to make sure the aircraft was in landing configuration. The video of the compressor stall on the original approach shows flaps down. (I don't see the gear down on that video, but my eyes are fallible.) The second approach the flaps are up. That means a switch was manually changed. Likely part of the go around. I just wonder if the bird strike happened just about where gear down should have been called and on the second attempt they lost track of the checklist items that had been done and still needed to be done. As Juan Browne points out the bird could have caused considerable smoke in the plane. He also points out the thrust reverser is deployed on that engine but not the other side. Damage from the strike? That could put some real panic in the flight crew. I also agree with him that the engines are producing power as the plane is sliding down the runway. All in all far too many things that seem wrong.

The ILS antenna only comes into play after it has hit the fan and just makes it worse.

Add to that that the plane came in the wrong indicated way (with the wind instead of into it) and touched down well long on the runway, both of which greatly increase the chance of calamity as well.

I checked it out with Google Earth, and the aircraft touched down almost 2/3rd of the way down the runway- even with the landing gear down, full flaps & slats & air brakes & reverse thrust it still wouldn't have been able to stop before the end of the runway, but probably (maybe) would have stopped before hitting the light array.

There appears to have been a whole lot of things that went wrong with that flight- such as the ADSB data cutting out before the initial attempt to land.
There's got to be way more to it than just a bird strike & landing gear problems.

The whole second/final approach was done in far too much of a hurry, about seven minutes before the "bird strike" and the fatal landing. Perhaps if they'd taken a bit more time, even by extending the legs of the go-around by a couple of minutes each they would have gained some vital time to get the aircraft into a better state. All I can think is that they were in a blind panic to get onto the ground....

... A blind panic due to smoke in the cockpit?...


At least on the 737 with the Leap engines (and other planes/engines?), I understand that a bird strike to the engine being used for the aircon can well push in blinding smoke and oil...

Was there other damage causing a blizzard of alarms and warnings?...

Or merely 'just' "inadequate training"?...



Hopefully details will be published very soon...

A few stray ducks shouldn't kill a plane full of people...

A close call.

Harrowing footage shows near miss on LAX runway.

Harrowing footage captured the moment two US planes nearly collided with each other on the tarmac.

A Delta flight nearly crashed into a private jet carrying the entire Gonzaga University basketball team on the runway at Los Angeles International Airport.

“Stop, stop, stop!” an air-traffic controller can be heard yelling at the plane carrying the men’s team as it prepares to cross a runway at LAX around 4.30pm Friday local time, according to The New York Post reported.

The rolling jet — Key Lime Air Flight 563 — comes to a sudden stop, just as Delta Flight 471, an Airbus A321, comes barrelling up the runway at full speed and lifts off.

“Woo! Woo! Wow,” a plane-spotter who was filming the runway and uploaded the video to Airline Videos on YouTube could be heard exclaiming just after the near-miss.

“In the years I’ve been doing this, I’ve never heard a ATC controller tell a plane to ‘Stop, stop, stop,’” the plane spotter added as the private jet kept rolling once the runway was clear.

The Federal Aviation Administration (FAA) has opened an investigation into the incident........

Now that is crazy.

The CEO of a tech start-up has shared the terrifying moment his self-driving Tesla veered onto light rail tracks in the US.

The CEO of a tech start-up was left “literally shaking” when his self-driving Tesla veered onto light rail tracks in Santa Monica, in the US, just as a train began barrelling down on the EV, footage shows.

Jesse Lyu, who founded AI-powered hardware company Rabbit, posted the alarming video to X on Thursday, and claimed he had to blow through a red light to “save my life”.

“It’s just f**king crazy,” he said in the video, as the car continues past the different train stop’s platforms........

Arn't checks done to tyres and runways before flights take off?

Flight disruptions at Melbourne Airport as Etihad Airways aircraft stuck on runway for 14 hours after tyres ‘burst’.

An Etihad Airways plane was stuck on the runway at Melbourne Airport for almost 14 hours after it was forced to abandon a takeoff on Sunday night and its tyres reportedly “burst”.

It meant only one runway was available for operations, causing flight disruptions during what is expected to be Melbourne Airport’s busiest summer for international travel ever.

Etihad confirmed its 6.15pm flight bound for Abu Dhabi rejected takeoff for “technical reasons”, while the airport confirmed the aircraft’s tyres were damaged, meaning the Boeing 787-9 could not be towed off the runway until repairs were done on location.

Melbourne Airport told news.com.au early on Monday morning that the 289 passengers on board disembarked the aircraft safely on Sunday night and were bussed back to the terminal, but the aircraft remained on the runway.

In an 8am update, Melbourne Airport confirmed the aircraft had finally been safely towed from the runway.

“Runway inspections have been completed and the runway has been reopened for operations,” an airport spokeswoman said.........

Boy oh boy are the press uninformed. Rejected takeoff, near V1, means very hot brakes transferring to the tire rims. Fusible plug temperature gone over. POP. Not the tire but the rim. Just as designed. Of course the captain should have vacated the runway so the fault would have been on a taxiway. I don't think the POH calls for fire service to hit the wheel assemblies with water to cool them unless there is a fire. POH does say park the plane for X hours before moving it after coming to a stop, no taxi to the gate!

Depending on the local rules the fire service may be required to cool the smoking hot brakes to something more acceptable.

As for vacating the runway rather than stopping on it, that depends on a whole lot of things, airline operating procedures, how the emergency braking systems are configured, airport layout and rules, and a few more...

Update.

Air safety investigators say high exhaust gas temperatures caused Etihad's aborted take-off from Melbourne Airport.

Australia's aviation safety investigator has revealed the cause of Sunday night's aborted take-off from Melbourne Airport by an Etihad Airways passenger plane.

Airport fire crews rushed to the runway and doused the wheels of the Boeing 787-9 Dreamliner after flight EY461 to Abu Dhabi "rejected take-off".

There were 298 passengers on board, some of whom reported being jolted by the sudden braking, but no one was hurt.

The Australian Transport Safety Bureau (ATSB) has just released new information revealing the flight crew observed a high exhaust gas temperature indication from the aircraft's right engine.

The ATSB said the rejected take-off was conducted in line with standard operating procedures.

"After gathering further information, the ATSB has determined it will not conduct an investigation into the incident," it said in a statement to the ABC......
