Vostok 5 and Vostok 6 were a dual flight, much like the Vostok 3 and Vostok 4 flights nearly a year before. Vostok 6 would land over 2 and half hours before Vostok 5. The two craft passed within 5 km of each other.

Tereskhova was the first woman to fly in space. There would not be another one for 19 years.
