UFO over Los Angeles : 3 black helicopters recorded next to a UFO

It appears that we are being watched from above. While renowned ufologists claim that extraterrestrial spaceships visit our planet on a regular basis, it appears that they are doing so more frequently.
Will this be remembered as one of the most critical junctures in the history of humanity? Are we being watched by advanced civilizations on a regular basis? Do the military fear these extraterrestrial civilizations and hesitate to attack, and how do they assess the situation?
On March 27, 2019, residents of one of Los Angeles’s outskirts witnessed an unidentified flying object that resembled a large dark sphere.
Witnesses gave an account of a spectacular flyby that was taking place from one moment to the next, without losing any detail of what they were seeing.
The person heard a loud noise from military helicopters that appeared at a distance from the UFO and apparently watched it. It was a sphere with no objective direction. As if they expected him to act.
A round sphere devoid of windows, rivets, badges, or any other characteristic of traditional ships, with the added benefit of being able to travel at high speeds.
It was reported that after a while, the spherical object was lifted and vanished, and the helicopters flew away immediately.
