Re: H2S isn't just a nasty smell
I think I vaguely remember reading about hydrogen telluride in Ignition!
"There are, after all, some chemicals that explode shatteringly, some that flame ravenously, some that corrode hellishly, some that poison sneakily, and some that stink stenchily. As far as I know, though, only liquid rocket fuels have all these delightful properties combined into one delectable whole."
Ah, no. The bit I was thinking of was discussing the use of butyl mercaptans as a rocket fuel. ...Apperantly the idea stunk.
