Aircraft Young planes Jay Jay (voiced originally by Mary Kay Bergman in Seasons 1-2, then later by Debi Derryberry in Season 3 and the reboot after Bergman's death and Donna Cherry in Jay Jay's Mysteries in the CGI/live-action series) is a small blue 6-year-old (originally brown in some of the pilot series) jet plane who acts as a twin brother figure. He is the titular character and main protagonist of the series. His basis is greatly based on a heavily modified Airbus A318. Tracy (voiced by Gina Ribisi in Seasons 1-2, and later by Sandy Fox in Season 3 and the reboot Jay Jay's Mysteries in the CGI/live-action series) is a small pink 6-year-old jet plane who is Jay Jay's twin sister and best friend. She has normal hearing but understands American Sign Language. Like Jay Jay, Tracy's basis is greatly based on a heavily modified Airbus A318. Snuffy (voiced by Gina Ribisi in Seasons 1-2, and later by Sandy Fox in Season 3 and the reboot Jay Jay's Mysteries in the CGI/live-action series) is a small green, later yellow propeller-driven 4-year-old monoplane who is a good friend of Jay Jay and Tracy. He is equipped for skywriting. In episode consistency (which depends on the order), one episode says that he has not flown further away from Tarrytown than Lightning Bug Lake, but other episodes show him flying much further; in "Grumpy O'Malley", Snuffy still has not gotten rid of his initial shyness, but in many other episodes, he shows no sign of shyness. Herky (originally voiced by Mary Kay Bergman in Seasons 1-2, and later by Debi Derryberry in Season 3 and the reboot after Bergman's death and Donna Cherry in Jay Jay's Mysteries in the CGI/live-action series) is a small (originally in some of the pilot series) yellow 5-year-old helicopter who is Jay Jay's friend. In the pilot series, he spoke with a stutter (like famous Looney Tunes character Porky Pig), provided by John William Galt, who voiced all the other characters. In the CGI/live-action series, he rolls his "R"s whenever he speaks. He has skids instead of wheels, and cannot taxi on the ground. He is based on the MD-902 Explorer. Ricky Rescue (voiced by Josh Keaton) is a yellow and red helicopter who acts as a teenage brother figure. He is known for his rescue duties. He is Herky's twin brother. Like Herky, Ricky has skids
