Sounds good, as it seems like the plane has a death wish and needs a software patch.

According to Keolis that runs our public buses in Stockholm, the buses should not go through the Klara tunnel.
"We have our driving routes. It would not have gone there. This applies to all of our buses that are so high. It is a clear instruction to our drivers."

The bus was out of service, so it may not have been driven by one of the regular drivers, and whoever was driving it decided to take a shortcut back to the depot...

Tell me tree branches don't sag from time to time and why put a bomb on the top of a vehicle? Same damn issue we have with gas tankers that have bottom valves that haven't been protected. It is the PINTO all over again.

Actually we swapped over to natural gas buses here back in 1997 with roof top storage (due to low floor wheelchair accessible designs) and as of yet have never had a problem with the actual storage system (the air-con systems would be taken out well before getting close to the gas storage), but gas connections at the engines have at times caused a few problem due to poor maintenance of the flexible connecting hoses. But then again we don't have such low overhead obstructions here either (double deckers are a different story though). Trees branches are deflected by the shielding.

Cheers.

At an end stop in Helsingborg 2012, a Volvo biogas bus ran at low speed into the rear of a stationary biogas-powered MAN bogie bus!

A petrol car does not explode - but a gas car can explode like on the movies. Gas vehicles are equipped with a safety valve which is to be discharged at a temperature of 110 degrees.
- Gas vehicles pose completely new problems for us, says Tommy Carnebo, firefighter and expert on vehicle fires.
- The problem arises when the safety valve does not work, then the vehicles become death traps. The worst example is when a gas-powered garbage truck in the United States exploded - the tank flew 400 meters and landed on a school yard, says Carnebo and continues:
- The risk area for a burning gas vehicle is 75 meters. When the safety valve is released, if it works, a welding torch also emits from the vehicle - six meters long from passenger cars, and twenty meters long from heavy vehicles. There is currently no regulations for how the valve should be directed, so it is not possible to know which direction the flame strikes. It is not so successful in, for example, central Stockholm, says Carnebo.
Carnebo calls for regulations from the authorities - partly for the placement of the safety valve and partly for clear markings on all sides of gas vehicles.

But as always, there is always things that you cannot test before you know what to test.

There will always be hiccups.

Sadly, fatal ones occur.

There used a difference between the Boeing use of avionics and the Airbus use, In Boeing's view the pilot was in control and the computer helped him. In Airbus view the computer was in control and the pilot was there to check its actions. In the Honeywell factory in Phoenix, which produced avionics for both firms, the engineers of the two sections were not to speak to each other even at lunch. Now it seems that Boeing has adopted the Airbus paradigm too, with unhappy results.

Yeah with airplanes that want to commit suicide, no thanks, I'd rather take a train over long distances.

All of China's 737 Maxes are grounded until further notice.

Some of the eight Italian dead were girls who had volunteered to help African women and children. This should not happen.

Yes. It's tragical.
Over 30 of the fatalities have been on their way to a major UN environmental conference in Nairobi.
Two of them was from Sweden.
But travelling is always risky no matter who is travelling.
Still flying is very safe.
15 aircraft accidents on major passenger aircraft occurred in 2018, with 556 deaths according to Aviation Safety Network's compilation.
And comparing that every year, more than 1.2 million people die in car accidents according to WHO.

A neighbor of a brother of mine in Genoa was a 737 captain. Every month he had to go to Portugal and take a a test at a flight simulator. If he failed it, he would have been fired. Why they haven't obliged pilots to train at a flight simulator on the 737 max?

Different countries, different rules.

Was listening to approach control at Los Angeles one day some years ago and an Areo-Mexico was cleared for a visual approach on a beautiful clear day. Next I hear the controller was asking Areo-Mexico if he intended to land at Hawthorn municipal or would he rather land at Los Angeles another five miles later, as he was descending too low. He obviously hadn't read the bold print warning on his approach chart telling him that Hawthorne municipal is on the flight path to Los Angeles and its runway points the same direction. Mind you the runway there is 1/4 as long and 1/2 as wide, and there is only 1 runway not the 4 at Los Angeles. He might have gotten stopped before he hit something, but they would have had to disassemble the plane and truck it out not to mention repave the runway. Once they had him change from Approach frequency to the tower, two other US pilots following him had some words to say with the controller about it. I believe shortly after that Aero-Mexico changed it flight manuals to say that pilots could not accept a visual approach to an airport and had to fly an instrument approach.

After the same aircraft type crashed in Indonesia last autumn the FAA issued this statement on the Emergency Airworthiness Directive (AD) for all Boeing 737 MAX aircraft.
https://twitter.com/FAANews/status/1060297106177622018/photo/1

Runaway Stabilizer
In the event of an uncommanded horizontal stabilizer trim movement,
combined with any of the following potential effects or indications
resulting from an erroneous Angle of Attack (AOA) input, the flight crew
must comply with the Runaway Stabilizer procedure in the Operating
Procedures chapter of this manual:
• Continuous or intermittent stick shaker on the affected side only.
• Minimum speed bar (red and black) on the affected side only.
• Increasing nose down control forces.
• IAS DISAGREE alert.
• ALT DISAGREE alert.
• AOA DISAGREE alert (if the option is installed).
• FEEL DIFF PRESS light.
• Autopilot may disengage.
• Inability to engage autopilot.

Boeing issued a safety update to pilots flying its newest 737 MAX airliner, warning of a possible fault in a sensor that could send the aircraft into a violent nosedive. That sensor measures air flow over a plane’s wings, but its failure can lead to an aerodynamic stall.
The plane in Indonesia crashed after the emergency system went wrong and activated the autopilot that steered the plane down.
The pilots then did not have enough training to take over manually and the plane crashed into the sea.
Boeing 737 MAX is not the first of its kind to involve a faulty “Pitot tube” a critical air-speed sensor that measures the flow velocity.
Makes you wonder if all airline companies got this information from FAA or Boeing...

Gary as one who has studied economics I disagree with that set of definitions. My courses in economic development lead to a very different conclusion. Oh well one can always get the answer they want if they set the assumptions.

“The plane was very close to the ground and it made a turn. We looked and saw papers falling off the plane,” Malka Galato, the farmer whose land the plane crashed on, told Reuters.

“Cows that were grazing in the fields ran in panic ... There was smoke and sparks coming from the back of the plane.”

The plane tried to climb but failed, then swerved sharply trailing white smoke and objects including clothes before crashing, said farmer Tamirat Abera.

If correct, sounds very much like a ground person failed to secure a cargo door and it came off in flight and/or cargo came out likely striking an engine or control surface. The other possible is a bomb on the aircraft, but I would have thought if that was the case the pilot would have said that to the controller and not, I need to come back, [to close a cargo door].
