That gets into some of the first principles of engineering a flying machine though. The hydraulics are your control for stuff like flaps and gear deployment. These things need to work consistently against pretty impressive forces, and you can only extend mechanical advantage so far before you start to run into issues with weight. Even having a backup hydraulic system would be a considerable amount of weight, and how else do you propose moving flaps and ailerons requiring hundreds or thousands of newtons of force to budge in the air?

There is a lot wrong with palm oil that has nothing to do with your waistline, and that’s what composes most of Nutella.

It’s not completely hollow, it has channels between the various holes that open and close selectively. The way hydraulics work requires everything to hold the hydraulic pressure, manifolds are where all of the various pressurized points meet up and get distributed to the various mechanics. If you can break that pressure seal at the manifold you can usually cripple the whole system at once. Most of a plane is run off of hydraulics, especially flight control systems.

One of the windows would be better. There aren’t a ton of places where a single bullet will take down a plane, if you can get a window you can at least depressurize the cabin and force a really sketchy landing, but guaranteeing the plane crashes when it’s full of people capable of keeping it in the air is no small feat. Maybe if you have access to the maintenance cabins you can pop one of the hydraulic manifold blocks, I’m not sure if the main ones have redundant fail-safes if the whole manifold spontaneously opens a new outlet.

A car without a clutch could also just be a funny car. They don’t really have a clutch, it’s more a bullseye looking thing that drops in stages. Basically if you try to dump 3000+ horses into first gear metal tends to explode, so you dump multiple stages that just roast until you get speed. You still have gears, but it’s less of a clutch and more of a time delay friction welding system attached to the crankshaft.

Not just the capacitors, the tube itself is a capacitor that handles multiple kilovolts, so you can easily hit the wrong side of the flyback transformer or poke the wrong part of the tube and get fried.

Not just an “Ouch, don’t do that again”, more of a heart just stops.

They are part of the deflection yoke. If you saw that chunky core wrapped in magnet wire on the skinny end of the tube that’s what that was. They aren’t always permanent magnets, most of the later model TVs used electromagnets, but it’s how the electron beam is moved across the screen. All of them will have very strong magnets somewhere by design.

It would be how the voltmeter would have been wired back then, you can damage the needle or it’s spring by pegging it for too long. Even then though, the only real issue I would forsee would just be the voltmeter spiking all the way to the right while it’s ringing, the chance of any real damage is pretty minimal. You can also check the datasheet on the meter, it should tell you what it can safely handle.

It’s looking like you are going to want to hook the volt meter up to your talk lines. I would test just probing the wires going to the handset, if I understand the schematic correctly the talk circuit is separate from the ringer. That being said, you can get a voltmeter that is tolerant of the voltage. In my experience anything under 400v is fine for most voltmeters, they use a resistor divider that have values in the megohms, the current passed across them is minimal.

As far as blinking on ringing, that one is super simple since the ringer is AC, just use an induction type detector to flash an LED on. Think along the lines of those screwdriver looking line voltage testers that light up when you put them next to a live outlet.

Edit: I should clarify what I mean when I say the ringer is on a separate circuit. There is a coil that energizes when the line goes up to ringer voltage that shunts power to the ringer and away from the talk circuit, so measuring the voltage from the handset or speaker should protect you from seeing the ringer voltage.
