Narrative:

The captain (who was the PF) while attempting to intercept J79 south of milie intersection, dialed in the wrong radial. This caused us to drift east of intended course. We penetrated W157A. Controller notified us we had penetrated the warning area. We corrected and intercepted J79. Both the captain's and first officer lack of awareness and lack of xchking each others' navigation, was the cause of this incident.
