UFO Sighting in Greenfield, Massachusetts on March 15th 2016 – lights pulsating

was driving from greenfield to turners falls, looked up n the sky was flashing, i thought it was heat lighting at first, but lighting dont act like this, the sky was pulsating, but only in one patch of the sky, then it would flicker n shut off like a like switch being flicked, then a minute later it would come back on n start pulsating again, and about 1 minute after it stopped i heard at least 2 fighter jets fly over, i felt excited, i love the unknown,.. the lights just stopped..
