CORONA 86 was launched on 1964 Oct 5 with a KH-4A payload. Mission 1011-1 was recovered on around Oct 9 after 85 orbits, with imagery of the USSR, China, Cuba and Zaire, but the SRV for Mission 1011-2 was not ejected; normal and lifeboat systems both failed. The inter-SRV fairing was confirmed to have ejected, but the SRV remained attached to Agena 1170, which reentered on Oct 26.
