Two F-14 fighter jets chased a large triangular UFO and disappeared, Puerto Rico, December 28, 1988

On December 28, 1988, at approximately 7:45 pm, a large triangle craft roughly the size of a baseball field was seen moving steadily along in the region near the naval air station in Puerto Rico, according to many witnesses (over a hundred). Three F-14s intercepted the moving UFO and apparently tried to force it to change its course. As the navy fighter planes engaged the large craft, it slowed down its forward speed almost to a standstill.
