Holy shit
Finding a loose solder joint and fixing it using nothing but a multimeter on a PCB with no schematics is nigh impossible without spending at least a few hours of testing, especially on old junk with traces you cannot see
Somehow nasa waltzes in and finds it in 2 seconds?
FUCK THAT
I spent 10 hours the last time I fixed a PCB, and it was still mostly functional beforehand so I could at least test it.
BULLSHIT from the author, broke immersion, 5/7
