1968-003A
Zenit-2 No. 59 was launched in Jan 1968 from Plesetsk into a 65.6 degree orbit. The Blok-I third stage entered orbit with the Zenit-2 attached, but the payload then failed to separate for the first 38 to 42 orbits, as noted in the RAE tables, because the pyro separation charges failed. This resulted in the depletion of the attitude control fuel and the flight was carried out in unstabilized mode. Reentry was attempted on Jan 24, but the trajectory was off course and the SA and PO remained in orbit with a low perigee. The APO system destroyed the SA over the Sea of Okhotsk on orbit 126. The PO continued transmitting until Jan 25. Many pieces of debris were tracked by NORAD, most of which reentered between Jan 30 and Feb 2.
