I can't say anything about mechanical and hydraulic systems. However, the
electronic units that the company I work for makes have large amounts of
lightning protection. Lightning strike tests are one of the standard tests
for qualification. I have seen transorbs take up a 1/3 of a card before

To be honest, the things we do to our units amaze me. Salt spray, full
functionality between -40 and +70 oC, vibration profiles over 7G acceleration,
EMC testing (some units have input levels of less than 10mV). We throw
ridculous enviromental extremes at the damn things and _still_ they work.

Aerospace is an unforgiving enviroment.

Yes. The prospect of imminant death does strange things to one's mental

I presume (for the purposes of lighting strike) that one can treat the body
of the plane as a Faraday cage.
