well, i listened to it for the fourth time and hear the voice said:

'привет народам нашей родины, прокладывающей человечеству путь к коммунизму. летчик-космонавт Комаров'

'privet narodam nashey rodiny, prakladyvayushey chelavechestvu put k kamunizmu. lyotchik-kasmonavt Komarov'

which means 'greetings to the peoples of our motherland that makes the way to communism for the mankind. pilot-cosmonaut Komarov'

lyotchik-kosmonaut is russian cosmonauts' title.

well, first i thought it's some official radio speaker, now i admit that it's Komarov himself before or during the flight. nothing like crying.

and, this appeal is copy-pasted two times and one time pasted partially, '-munizmu', which indicates the fake.

the radio talk in between is illegible for me
