The Titan program was terminated specifically after the explosion in Damascas Arkansas. However the issues aassociated with the handling of the propellants always made the program problematic through it's lifecycle.

BTW I'm a Minuteman III weenie by training and we also had to deal with MMH and nitrogen teroxide.

I hate the limitation of chemical fuels, but nuclear ones tend to leave a blasted radioactive wasteland of the launch site. I like the Larry Niven solution: air compressed almost to neutron degeneracy. Is that possible? Not now, maybe later.
