I was laying in bed when I hear a strange sound and my dad and my brother who are on the studio shout to me that something is passing by at fast speed. So I opened the window and saw a missile like aircraft that looked small , passing at very fast speed above our building. It was dark or grey, but it was midnight so It was very difficult to see it on details. I was shocked and surprised by this object and its speed captivated me, its sound was like a bomb being dropped or a missile launched. I felt like something was spying on us or doing recon on the area, I didn't feel fear since my dad said it could be a us government drone. The object went fast from the sky in straight direction to the mall near my house, at a low speed, we thought it could collide then disappeared mid-air.
