Also, even if it did fall out the bottom of Cloud City like Luke did, there’s no reason to think it couldn’t have landed on some kind of mining platform lower down in the atmosphere.
IIRC, the old Marvel comics had Bespin with a marshy swampy surface. The Ugnaughts lived down there and had airships that used Tibanna gas.
Interesting, because this is also what Bespin was like in the Leigh Brackett script. There were some aliens living on the surface whom Luke befriended and who were friendly to Lando.
