According to the FAA N number registry, it's a Moni that was
registered in 1989, and cancelled in 1992. *The acft is shown as
"Destroyed"http://registry.faa.gov/aircraftinquiry/NNum_Results.aspx?NNumbertxt=...

I don't think it is a Moni (they all had an engine!) and also suspect
it is an earlier ship than 1989 - 1970s vintage is my guess.
