In the Ensign$-$Bickford case, which I discuss in my recorded lecture, the Connecticut Appellate Court held:

The Defendant was liable for negligence.

The Defendant was not liable for the plaintiff's injuries because the plaintiff was a mile away, so it was not reasonably forseeable that he could be injured by the explosion.

The Defendant was strictly liable because it engaged in an ultrahazardous activity.

The Defendant was not liable. Even though it engaged in an ultrahazardous activity, it did so legally and with insurance. Thus, it could not be held liable.
