On the night of March 24th, 2017, I'm on my way to pick somebody up from work at approximately 11:15pm, heading south on the highway (route 3) just before you reach Nashua, N.H.. I clearly witnessed a MASSIVE green beam shoot downwards from the sky at a slight angle, flicker a couple of times really fast, and then it vamished. There were what looked to be balls of light, or something to that effect, floating withing the beam itself. It was roughly a half mile to a mile from the nose of my vehicle. I did not see the original source of the green beam, nor did I see it's destination. However, I did witness the entire incident from beginning to end. There were a few other cars travelling the same direction and were within 100 feet of my vehicle. The color green of the beam was a pastel-neon type of color. Very bizarre. The thickness of the beam was easily 24ft x 24ft. The length of the light itself had to be a mile to a couple miles long. Like I said...it was MASSIVE. Very out of place. Very odd.Feel free to contact me if you have any questions. Thank you for your time, as it is much appreciated.
