Lionel has appeared in every episode of Budgie the Little Helicopter.
Lionel appears to be inspired by a Westland Lynx helicopter. This type of aircraft was designed as a multi-purpose military helicopter, which could explain why Lionel takes his responsibility seriously. As of 2009, 450 Westland Lynx helicopters have been built.
