Gabbert, 33, was out Jet Skiing with his two younger brothers, Tyler and Brett, when they came upon a submerged aircraft with a pilot and three passengers -- the Hupp family -- who had just plummeted from the sky upon approach to Peter O. Knight Airport.Gabbert's brothers, visiting him from Missouri, discovered Wesley, Lisa and Hunter Hupp and their pilot all alive, but visibly shaken and covered in oil.Gabbert, who said he has spent 30 years of his life on the water and considers himself a strong swimmer although he has never taken a formal water safety course, instructed them on how to inflate their life jackets.The pilot, who remained in the water, held onto Gabbert's Jet Ski as the Tampa police marine patrol unit arrived and Gabbert was able to gently guide him to their boat, which was about 250 meters from the beach."Anytime you can find a guy who will drop everything and go help somebody else that he doesn't even know without even thinking about it, and take their life into their own hands and helping somebody else -- saving their lives -- that says a lot about the guy."
