This was seen this week and recorded over Miami, Florida, looking northeast direction from Brickell area. It started as a single light that was changing between what looks to be white and red colors, hovering over the city. Then another one came into the sky and they seem to have started interacting together. Eventually it got a bit scary because one of them seemed to have started to approach the individual recording it.
Very interesting. After doing some research on YouTube, other videos are found that show a very similar occurrence. Yes, it is possible to be drones, but is it likely? Until it can be identified, it is still a UFO. The objects have seemed to also project sounds described as hissing or wobbling sounds that had a low and high pitches. However, those sounds were also being heard along with the city noises that are always there, so disruption of actual sound was probably created.
This video was recorded at approximately 10:15PM EST (daylight savings). The other videos found on YouTube are during day light, but look just like these flying objects.
