"In 1996 I came across a turbine ground power unit (GPU) that belonged to a NF 5 jet fighter. The same type is also used as a auxiliary power unit (APU) of a Fokker F28 . I bought it for 2000 guilders not knowing what to do with it. First I planned to put it in my Trabant P601 car but the idea was abandoned in favour of a turbine motorcycle.
