"The launcher started to disintegrate at about H0 + 39 seconds because of high aerodynamic loads due to an angle of attack of more than 20 degrees that led to separation of the boosters from the main stage, in turn triggering the self-destruct system of the launcher"
"At this point, the northern-most Solid Rocket Motor (SRM #1) separated from the core booster, initiating the Inadvertent Separation Destruct System. At 45.529 seconds, approximately 3 seconds after the automatic destruct sequence, Mission Flight Control Officers sent command destruct signals to the vehicle."
Up until a few months ago, I was an engineer for OSC. We used the same Flight Termination Logic Unit (FTLU) as Antares. I can confirm that it can provide for automatic destruct should the engineers desire it. I have no knowledge of the specifics of its use in Antares (I did not work on the Antares program), but given the constraints of operating from Wallops, I would not be surprised if automatic destruct is enabled for all Antares launches.
Ariane 5 (the infamous flight 501) self-destructed.

A SpaceX rocket self-destructed:

"In a statement, SpaceX says the rocket detected an anomaly and automatically initiated its self-destruct sequence."
The Titan IVA-20 explosion was also due to a self-destruct, and not the range officer:
