Flying is a misnomer. They're more like leaping fish, or gliding fish, to be honest. When they feel threatened, they swim really fast and launch themselves out of the water. Their massive fins enable them to stay there long enough to seriously confuse a predator. And no, they are not 'the missing link', although that's a nice idea. Wings as a method of leaving the ground have evolved several times in nature.
