This camera footage was shot on in Glen Rose, Texas, USA on the 28th of December 2017.
The cameraman was filming an airplane with an infrared camera when suddenly he captured a UFO flying towards the airplane. When the airplane crosses the UFO the mysterious object disappears. The camera tries to lock on the object after it disappeared, but it was just gone. It’s like the object was able to cloak itself. The thing is that objects filmed in infrared, don’t just disappear, unless they really disappear… so the question remains what this mysterious object was?
