This is what i just posted on the minnesota mufon facebook page and is my best description right now ..We are in our house right now too scared to go outside and frankly in shock ..We are in a rural area did anyone see the 150 or so lights going across the sky in central minnesota not an hour ago ? in formation in a row high in the atmosphere one after the other for almost twenty full minutes...I am a skeptic and i saw this tonight i was not sure what i was looking at then came four in for mation and as they got above our house about a mile up i could see the shape of an actual craft must have been hundreds of feet across...Then i called my friend who lives a mile away and asked him to come out and witness this my wife also saw it...And i kid not while i am on the phone with him two craft rise up our of the swamp not 300 yards from our house no lights silent huge black shapes about 50 feet across up to about 200 feet in the air ..I am going nuts on the phone wife is screaming..By now then they get this grey type of haze surrounds them both and all of a sudden they just move of from zero to what must have been mach 1 then faster silent and across the sky and gone...As i said i am / was a total skeptic ..This has changed my life in an instant ....Not sure what to say else but we are in the house now and both in shock and don't know what to think or do so i just got on here to write it down for you ...As a reaction ...No not drinking or drugging totally sober sound and clear ..I know this sounds nuts but i just witnessed it and so did my wife
