Kamanin considered Tereshkova as the leading candidate for the first flight, with Solovyova as her back-up. In personality they were equivalent to Gagarin/Nikolayev - indeed, Tereshkova was considered 'Gagarin in a skirt'. Ponomaryova and Yerkina were equal candidates for the second female Vostok flight. The group would go to a resort in the Urals from 30 November to 10 January. The final decision as to which one would fly would only be made 3 or 4 days before the flight. References: 376.
