If I recall correctly, Boyer sold to 16-18 airlines before selling APS to Wencor (though I think some were actually announced after the Wencor buy announcement was made). Seems it was at least 12-14. I checked edigerati, and that matrix of airlines/adoption dates is no longer there. I referred to this awhile back when criticising Wencor/digEcor`s sales record - and the number I used then (probably after checking) was 18 (i.e., Wencor had only added a few in over a year`s time).
But I KNOW nuttin`!
