Two bright object, one in pursuit of the other

PL> Domes Beach, Rincon  PR Time> Around 9:oopm Date> April ??, 1983 (same day FRank Marino & Mahogany Rush was playing a concert    in San Juan) One light traveling N to S just above moon. My friend and I thought it was a plane, a min later, the same object appeared againt traveling in the opposite direction, same path. When the object passed the moon, another bright object appeared out of no-where.
The second object appeared to be in a pursuit of the first object because it picked up speed while object two was zigzaging at a very high speed until both objects just disappeared...
