The Knight Industries Cargo Plane is a plane owned and operated by the Research and Development Division of Knight Industries. It functions as a mobile garage for the K.I.T.T. and as a mobile Headquarters for employees and operatives of the Satellite Surveillance Center. The cargo plane fills most of the same functions that the F.L.A.G. Mobile Unit served in the original series. The cargo plane meets its demise in Day Turns Into Knight.
