Translation: 
Dhruva Mahārāja saw two very beautiful associates of Lord Viṣṇu in the plane. They had four hands and a blackish bodily luster, they were very youthful, and their eyes were just like reddish lotus flowers. They held clubs in their hands, and they were dressed in very attractive garments with helmets and were decorated with necklaces, bracelets and earrings.
Purport: 

The inhabitants of Viṣṇuloka are of the same bodily feature as Lord Viṣṇu, and they also hold club, conchshell, lotus flower and disc. In this verse it is distinctly stated that they had four hands and were nicely dressed; the description of their bodily decorations corresponds exactly to that of Viṣṇu. So the two uncommon personalities who descended from the airplane came directly from Viṣṇuloka, or the planet where Lord Viṣṇu lives.
