You sound like you have a problem with that, but I can't fathom what alternative course you'd rather them pursue.

It is just a note. I don't mean it to sound anything other than what Wikipedia itself states. I see a tonne of "Wikipedia agrees" but none of "Wikipedia is a living document" and it isn't its place to be a gospel of truth...

The phrase "Wikipedia agrees" succinctly encodes the correct degree of confidence, as opposed to "it's true, see Wikipedia".

I read a story about the "landing gear down" button being close and similar to the "shut off all engines" button in some bombers during WW2. A few of them crashed after very long flights, on approach of the runway. Inexplicably, they suddenly felt right when they should have deployed landing gears. So aircraft makers learned from that incident that no amount of training can mitigate a bad user interface. Especially i…

That was the "flaps down" switch, not "shut off engines". The key feature of fixed-wing aircraft is being able to glide unpowered; dropping the flaps however would be equivalent to yanking the yoke all the way forward.

But during a landing you would normally have the flaps down, this is exactly what they're for: to enable lower approach speeds and more visibility of the runway due to a nose down angle

Just noticing the medium author, this guy posts fantastic breakdowns of plane crashes on r/catastrophicfailure Have to say the simulator part makes me lean heavily towards the pilot crashing it purposefully, from the article - "The most widely reported piece of evidence tying Zaharie to the disappearance was a course he had charted on his home flight simulator about a month before the crash. Zaharie had a number of h…

It is very strange. At the same time I imagine a lot of actions in flight simulators are odd choices you might not make in real life. I know I did a lot of poor flying….

As a trained pilot, flight planning is a huge part of your job.

Navigation is also a big part of the job. if you assumed you had to turn off parts of your nav equipment to avoid detection, then visual reference (ie flying the path to visually memorise/familirise yourself with wayppoints) would be something you'd certainly do - and a flightsim would be perfect for this.

Radar is not exactly “new” technology, to your point I wonder why airports are not equipped with one. Shouldn’t break the bank. Plus don’t militaries have radar anyways for air defense? How is it possible that no radar from multiple countries picked up a silent Boeing 777 flying to nowhere?

I think it's most likely that governments with radar in the area don't want to admit they have it.

I doubt that. Radar is extremely easy to detect. Anyone who wants to know about it will know it's there.

Huh? A lot[0,1,2] has been done considering how little we know about what has actually happened and a trivial search would enlighten you. Also, real-time streaming of GPS position for the thousands of flights in the air at any given time is not a trivial problem (but technology is improving and ICAO is pushing for such solution[3]).

Satellite phone text messages cost about $1 each. Sending one every 5th minute seems sufficient. That's $120 for a 10 hour flight. Seems technically quite doable with existing technology at a reasonable price? I imagine there are optimization that could be done to reduce the cost further. Big customers with constant rate usage can probably negotiate a more favorable price etc.

Iridium short burst data messages are much much cheaper in bulk than that :)

Investigations have some weird bits. I've always wondered if there's a certain title for the person who prepares the chickens for the 'chicken gun' in airplane testing. https://en.wikipedia.org/wiki/Chicken_gun
