Red-orange orb, changes shape vertically into glowing teardropAfter viewing fireworks set off from a boat in the middle of Premium Millpond, and after the sched New Rochelle Fireworks show ended, which we were able to view from a distance, The sky was clear. There was a lot of air traffic (planes and helicopters) due to airports nearby towards the city on and off throughout the night, but the sky was clear, very dark a the time my fiance' and I saw a glowing red light moving very slowly towards our direction (coming from the south) over the trees I believe had to five island park. As it got closer we noticed that there were no other lights, just a red circular round glowing orb, the outline of it was red and the inside was more of an orangish red color. As it moved even closer it started changing shape, by "stretching"? Downward almost like a teardrop until it was completely vertical, like a very short thick laser beam, it had a very wierd glow around it, It than went back up into its orb like shape. It ! did this same teardrop thing two or three more times as it moved across the sky (very low) To the right of us (east). At last sight of it the red orb was very big and bright, it bursted out in the way a firework would in the sky, but than it came back to shape very small and orange colored and just disappeared. We recorded it, but on the video where the orb morphes ito a vertical beam like thing, the camera captured a completely different maneuver. It looked nothing like it did as I saw it in front me. Both the sighting and footage showed an object doing things that are completely unexplainable.
