As you can see, players can successfully fly while they are dropping some items (in this case, these are wool-blocks) (if there is nothing to throw, the cheater cannot continue flying). During the flight of the cheater, AAC constantly makes small teleportations (perhaps this is one of the reasons why this cheat works). Unfortunately I don't have this cheat client. But I have messages about teleportations caused by AAC as well as information from the aac_events table.
