The term to "go ballistic" probably originates from guided missiles. A guided missle that loses it's lock will go ballistic, that is to say it becomes an unguided missile, likely to cause damage wherever it lands. Hence the use of ballistic to describe someone who has lost control and flown in a rage.
"You must keep the target inside the HUD or the missile will lose lock and go ballistic."
"If my mum finds my stash of porn she is gonna go ballistic."
