Metatron:
I had a UFO experience exactly 6 years ago. It was witnessed by 12 people. Three were family members. Five were JW-s from two different families that live about 5 miles apart but on the same trajectory. Three "worldly people" - a family that lived next door. One woman who lived accross the street.
It consisted of a sound like a squadron of Jet Airplanes just above the house. The sound started in the SW and moved NE. It lasted 20 minutes. It was so loud the whole house rattled. Even in my basement office where I was working. My wife had hearing problems the next day - she was on the top floor. My son saw a bright sun-like object streak accross the sky in the NE after which the sound (which had been unbelievably loud for 10 of the 20 minutes) stopped abruptly. Other witnesses of the sound were on a line up to 5 miles SW of our house.
On the night this happened MUFON reported their busiest night in UFO's all accross the US.
Reports of similar "loud sound" experiences have been reported even back to the mid 1960's. Some of the loud sounds have been accompanied by observance of huge (300 feet long) craft just a couple hundred feet off the ground that suddenly took off in a flash and disappeared.
Ezekiel 1:24 "And I got to hear the sound of their wings, a sound like that of vast waters, like the sound of the Almighty One, when they went, the sound of a tumult, like the sound of an encampment."
Was this a blimp with a 1,000 watt amplifier? Kind of an expensive practical joke.
Is this some secret US technology? Going back to the mid 1960's? What's the purpose - scare people in a major metro area?
I am inclined to think that these craft are moving slow - either because they are going through some kind of refractory period to accumulate enough energy to carry out some critical maneurver or to make sure that they link up with some kind of coordinates or perhaps a beam. I personally don't believe these are necessarily genius level entities arriving from some huge distance. I think it makes more sense that there are parallel universes and they have discovered some fairly simple way to "jump" between various worlds.
