What flew over Miami – a UFO, a comet, a rocket?

Residents of the city of Miami Gardens located in Miami-Dade County, Florida, USA, reported that today, June 29, 2018 at 5:30 am over the city flew an unidentified object.

It is difficult to accurately determine the belonging of a given object to a specific event. In appearance, what happened in the sky over Florida is like the flight of a comet, a large meteorite, the entrance into the dense layers of the atmosphere of space debris, the consequences of launching an intercontinental ballistic missile or even a UFO flight.

The launch of ballistic missiles, which are often observed in the sky over Russia, are always accompanied by the appearance of a spiral glow in the upper layers of the Earth’s atmosphere, but in this case everything is happening in the US and the rocket engine technology there is completely different, maybe it is the launch of a ballistic missile, but why does it fly on Direct trajectory, but does not go into the upper atmosphere?
