Again UFO Morovis Area - Puerto Rico

These are four photographs of what apparently was an airplane. But before taking these ones, I saw what it looked like and oblong bright object, so I ran to get my camera but it was too late, the object vanish.
Then later I see that an airplane is passing by again, and since I had my camera that I got minutes later, I decided to take a couple of shots just for fun. And what a surprise I got to find out that that airplane turned into something “”else?””
Take a look and these photos and you decide if this airplane is a ufo.
