The Flying Ford Anglia was adjusted by Arthur Weasley to be able to fly, as well as
become invisible with the use of a specially installed device called an Invisibility
Booster. The car was used in 1992 by Fred, George, and Ron Weasley to rescue
Harry Potter who was locked up in his room at the Dursleys and was unable to
receive any mail from the Wizarding community as a result of Dobby's attempts to
protect him.
