Polish national hero, General Mirosław Hermaszewski (1941-2022), first Polish space traveller, who flew on Soviet Soyuz 30 in 1978, gave an interview before he died, in which he answered a sudden joke 'flat earth' question with totally serious demeanour, saying, yes indeed the earth is flat

Video of the Polish cosmonaut saying this, short vid including the famous clip where Buzz Aldrin admits to a little girl that humanity never went to the moon
