Dynasty22:
Years ago, Zantop Int'l Airlines operated various fleets through YIP: the Convair 640, Lockheed Electra (L-188) and DC-8s. I jumpseated in '84 on a Zantop Electra from there to ORD, in order to connect there with MVA for groundschool in the Quad-Cities on the Shorts 330/360.
Based upon what I read, Zantop was a decent operation, and never understood why they closed the business down. A number of pilots seemed to be working there as a career. One of their Convair Captains came over here.
