The Premonition

S2, E16: Under instructions from flight control director Baldwin test pilot Jim Darcy executes a maneuver which causes his supersonic plane to exceed heretofore known velocities. The plane goes out of control...Darcy prepares for a crash landing...and at the same time his wife is racing to the scene. Suddenly...time stands still. The world about them is frozen. Darcy's guess that a time barrier has been broken is confirmed when a limbo creature appears and threatens to prevent the Darcy's from returning to the animate present.
