Torres,
When I left NCA in 2001, P2-ISL, ISM and DWA were all still chugging along quite nicely. In the sense that their wings were still attached (just - the ripples in the upper-surface skins were of some concern) and the engines worked more often than not!
I believe that ISL and ISM were both ex-Talair, but DWA might have come from a different stable ("Divine Word Academy" or an institution like that?). It was a 260HP BN-2 with single, not dual controls.
