[sdiy] uA726, heated pairs (slightly OT)

[Paul Higgins]

Hi all,

I have a question that is probably a bit OT, but here goes...

I recall reading somewhere that one of the main apps for the uA726 was 
in, of all things, ICBMs (and other rocketry/aerospace stuff).  Forgive 
my ignorance on these matters (I'm no aerospace engineer), but why the 
heck do you need a thermostated matched pair in a missile?  I really 
found that kind of bizarre.

Thanks (and sorry for the possible waste of space)!
