You are of course, correct. My first engineering job fresh out of university was for GE. I worked at a (big) site in the British countryside in the Midlands. One of our clients was Boeing, and we made a lot of sensors for them: anything from landing gear stuff, cabin oxygen and pressure sensors... you get the picture. Quite a lot of them were ultimately destined for the 787. I also remember manufacturing sensors for Hamilton-Sunstrand... who would then fit them in 737 rudder assemblies and then sell them to Boeing. The whole subcontracting business was very byzantine in its complexity! I also distinctly remember Boeing execs coming over very frequently to give updates, feedback, etc.
