About air flying in Russia

The provincial Russian town of Nerekhta is celebrating its 775th anniversary. The basis of the holiday is the legend about the local craftsman Krikutny, who was the first in the world in 1731 to fly in a balloon. Was there really the balloonist Krikutny, or was this story invented by the provincial official Sulukadzev? Whom to believe? To the text of the charter for the first ballooning or to historians who refute the reality of this event?
