An expensive product that's probably just one component in a box.........

Bud:
It is not your grandfa's axial resistor in the 50 Ohm cal standard. Also, try disassembling an industrial cal standard and let us know how easy it was.

I remember one: Was looking at a faulty manifold pressure sensor in a racing plane and why it failed. Opened it and found that it's basically a through hole part from ST in a milled little box (4-wire - power supply and diff out). The part cost was 10€, but since the sensor was FAA certified, the sensor costs some ~300-400€. Go figure... Maybe I'm in the wrong business :) To be fair, certification is kinda expensive.
EDIT: Found the sensor. It seems the price went down a little. https://www.aircraftspruce.com/catalog/inpages/jpimanifoldpresssense.php

Good example, although it looks like two parts in the photo. And one of the parts must have had an aerospace connector on it right?

That's the messed up part: It had 4-pins sticking out so you can connect a 2.54mm header onto them! On a FAA cert part in an acrobatic/racing plane. I thought it was a joke.
