I logged a lot of BIS time in the RV Electras over the years, and thought you might enjoy this video covering some Electra flights in the late 1990s, including ops at SDP and DUT. Both airports needed their runways lengthened in the '80s in order to accommodate bigger planes than the RV YS-11s that had been used previously. This was very expensive because water depths at both ends of both runways were very deep, but political lobbying by many, including yours truly, eventually got the State to cough up the required funding. (I had stopped working in the region before the projects were complete.) Ironically, RV went tango uniform shortly after this video was shot.

In the part of the video shot from the cockpit at DUT you can see a Grumman Goose parked on the ramp. I was on that plane's predecessor when we ground looped on a wheels-down landing right at that same spot in the early 1980s. (The plane I was on later crashed, claiming two lives.) Yahoo, ride 'em, cowboy!
