They plied their trade between Ft. Lauderdale, W. Palm, Grand Bahama, Providenciales (Turks & Caicos) and Cap Haitien, Haiti, in superannuated DC6-Bs.
One time in Provo they couldn't get the inboard port engine on the plane to crank -- so they offloaded everybody, the pilot took the plane down to the end of the (coral) runway, stood on the brakes, revved the other three engines up to top speed, popped the brakes, roared down the runway, successfully propped the dead motor, and then taxied back into the 'terminal' (a corrugated shed populated by chickens and the occasional stray dog). We climbed back on board with SOME trepidation -- but, hey, that was aviation in the islands in the 60s!
