I live in a 8 stories high apartment, so I was able to see the whole event without anything blocking our way. Although you can't see the light trails in the video, this thing accelerates, it shoots off with a long streak of light and the speed was nothing you can find in this planet, unbelievable.This thing is only visible in the camera when it stops or hovers, or when it starts pulsating some sort of a light to accelerate. Guess when it shoots off, there's not enough light source for a digital camera on a 30fps video mode.For those debunkers out there: what we saw that night, we saw what we saw. You can call it birds or bats... don't matter to us anymore what you all will say.For those who saw something similar or even more dramatic, probably care less what others think as well...
