LOL? So it's easier for you to believe that little green aliens from another planet landed in England in 1980 instead believing that some sleepy, tired, and confused airmen away from home at Christmas-time got confused over seeing flashing lights through the trees in a dark forest? Now, that is "LOL"-worthy.
How do you explain that the tape syncs up precisely with the rotation of the lighthouse beacon? How do you explain that the color of the light being seen was the same as the lighthouse? That it was seen in the same direction as both the lighthose and the lightship? That it "moved behind the trees" when they moved, but stopped when they stopped? Did you ever look at the moon behind some trees while in a moving car?
How do you explain the fact that the men described the light moving back and forth? The plethora of different colors they observed? The fact that the witnesses described the light/craft coming towards them? The eyewitness accounts of a physical craft on the ground? The sudden liftoff and takeoff of the object?
I enjoy visiting lighthouses on both the Atlantic and Pacific coasts, and have been near them in all sorts of weather (fog, chills, snow, night, strms, etc.). I have never mistaken a lighthouse beam for a completely inexplicable aircraft.
It doesn't add up to a lighthouse.
Is it normal for a lighthouse to have red, white and blue colored lights?
