I don't think that's how airplanes on aircraft carriers work... maybe I'm wrong. But the only device I can think of that should be there is the one that grabs the planes to stop them when they land to keep them from crashing in the water. Which would mean the door got angry over the years, and vindictive, and finally when his time came, instead of catching the plane and saving all the people, he launched the plane and all the people inside to their deaths in the water...
But yeah the door is just angry and killing people now.
