Just to balance Archibald's one about nuclear rockets 
It's noted in the BBC article here that the bloke who invented the CND peace symbol originally considered basing it around a Christian cross. Because many of the anti-nuclear and pacifist groups, especially in the 1950s when it started, were church-based.
WI he had done this instead of using the OTL semaphore-derived one?
The main change from OTL I can see from this is that groups in the USA may be less hostile to it - in OTL there were all sorts of funny theories about it being a Satanic symbol or something.
