 back to Moscow to work for Stalin. And I think it was 1943. It was during the war. And Stalin realized that by sending, he had either killed or banished basically all of his engineers and scientists. And he realized midway through the war that maybe he had made a rash error there and needed a few of them back. So they were all ordered to come back, but no arrangements were made for Kirolyov. So he just started walking.
