Re FireLight's comments on the Kelowna airport viewed from Google Earth.
Kelowna Flightcraft is a group of companies, one of which operates the Purolator Courier air freight service using Boeing 727 and Convair 580. The airframe division also did the stretch Convair 5800 freighter conversion, and does the cargo door installation on CV580s as well. Check out their web site at flightcraft.ca.
