To find out what one is, if you still have a CRT monitor on your
computer, go into the Setup and look for the degausser, and press it. It
may be represented with a picture of a magnet crossed out - which is
what it does - it demagnetizes the shadow mask (or aperture grill if you
use a Trinitron) in your monitor. Your monitor will go
BBbbbbbBBrbrrrrrrrr! when you hit it, and the picture will wobble around
a lot for a couple of seconds. (Some monitors degauss on power-up, and
that's why they make the noise they do when you turn them on).

I assume they think the steel parts of your plane have become
magnetised.
