nauseus

That's the BTS.

Well covered there eh? Maybe it was a gold member.

It's not what you said. So no need to thank me. Thank you.

Yes, bloody horrible.

There was no third pilot according to the manifest. If someone else as there it had to be a "guest".

Better to differentiate between tidal ranges and sea-level variations.

They have but Bangkok and surrounds has a coast that was formerly mainly mangrove swamp - low elevation soft mud and sand - not a great foundation for dikes and with no existing high sand dunes to help, as the Dutch have. To protect Bangkok, it looks like that a huge area to the south would have to be contained in the northern part of the Bight of Bangkok.

Time to take a big breath, then.

I doubt that but there are hundreds of similar (looking) switches for numerous applications so it could be possible to install a wrong switch type that does not have the locking feature.

Yes, the FAA SAIB NM-18-33 mentions 737 airplanes with fuel control switches being installed with the locking feature disengaged but does not explain the actual meaning of that. It later lists other Boeing models with different but similar toggle switches recommended for each. These switches are advertised as military grade and probably last for decades but may break or get damaged like anything else. The final paragraph of the recommendations section eventually says: "we request that owners and operators report any failure of the locking feature of the fuel control switch to Boeing". This is the first use of the word "failure" in the report and implies that the switches should be initially installed as the specified, functional (lockable) units, which must be the case. There is no definition of the "disengaged", what that means, or if it's even an option?

Or known problem? This issue has been known of for as long as I can remember but fast development has still been allowed, like: Billions of tons of hotels, pillars, commercial towers and condos etc. all pushing down on the clay. Klongs filled in and inadequate or difficult drainage routes. Cement and concrete everywhere impeding natural water sink inlets. But I still love the place and hope it survives.

I've just looked over the specs again but no help. So, show me how the locking feature can be disengaged, please?

You've just heard? Great.

This leverlock type of toggle switch is equipped with a spring-loaded locking mechanism that keeps it at the position set by the pilot. The mechanism prevents any other unintended switching. The switch has to be pulled up (away from the pedestal surface) before moving it from run to cutoff, or vice versa. Then the spring draws the switch contact down into the desired position. This switch is built as one unit and there is no selectable option to "disable" it without physically dismantling or damaging it. This type is widely used in other electrical/electronic equipment and they are what they are (see below): https://www.reuters.com/graphics/INDIA-CRASH/TIMELINE/xmvjelqwlpr/

Maybe your ears work uni-directionally?
