3, 3-4 inch red circles - in a straight line - equal distance apart in sky, to outer atmosphere, 2 seconds, in order. 4th after.

3 red lights, in a straight line, equal distance apart appeared in night sky, altitude appeared lower than planes (I live near the MSP airport) no blinking lights, no sound, no movement, from my vantage point appeared 3 to 4 inches in diameter, for 1 minute, 1st in line within 2 seconds went into the outer atmosphere, no acceleration, no noise, 1 second stop and appeared as a pin head size red dot, then disappeared. 2nd in line, same process then 3rd in line, same process. I went into house, got cell, went back outside, called brother, gave description of event when a 4th red light, same size, same position hovered in the same spot for about one minute, within 2 seconds, same process as previous 3, no acceleration, no noise.
