Video Explanation

Every plane, whether it is private or commercial, is issued a registration number similar to how cars are granted license plates. The term “tail numbers” refers to the identification marks that are normally visible on an aircraft’s tail (thus the name), or, in the event of many private aircraft, on the engine cowling. Similar to license plates for cars, registrations can be customized. Private planes present a unique situation in which there are no real restrictions on where you can register your aircraft. As a result, some rather obvious custom tail numbers have emerged:

Nike Corporation – N1KE
John Travolta’s Boeing 707 – N707JT
Lord Alan Sugar – G-SUGA
N999BE – is found on one of Bernie Ecclestone’s aircraft
