Does the shuttle have to comply with RoHS?

NASA - "Damn, I knew we shouldn't have gone with that lead-free solder. Oh well, we'll get it right on the next shuttle - too bad about the crew though..."

Military, medical & aerospace electronics are all exempt because the dangerous unreliability of lead-free solder are all too well known!!!!!

We'r just waiting for the misstake that someone put a RoHS board into any of these kind of application areas. Like wifi/gsm equipment in airplanes, that need to source power somewhere. Or careless repair ppl ;)

Whats NOT funny is that these risks are VERY real. Not just tin whiskers, but also the vibration causing joint failure.

Remember, for a lot of electronics, the government has a COTS mandate (in order to save money).

Airplanes have these things called circuit breakers....
COTS toys short out - breaker pops - boring but safe flight

Suppose someone mixes up replacement material for more critial equipment ..?
You also have the medical arena, automotive electronics, or simple whisker prone electronics controlling non-whisker prone one. Like a PC controller..
