1970-088A
The final L-1 flight was intended to develop technology for the L-3 program. 11F91 No. 14 (7K-L1 No. 14) was launched on 1970 Oct 20 and named Zond-8. The attitude control sensor failed during reentry; a ballistic reentry over the North Pole led to a splashdown in the Indian Ocean 730 km southeast of the Chagos Archipelago.
