Rectangle object seen over São Paulo in Brazil while the blackout in big part of the countryI went to bed pretty early that night cause the energy power was cut off. I layed down in my bed to check emails and schedule on my cellphone, and about 0h45 i observed through the window some lights flying above my building. I ran to the window thinking that could be an airplane, but the air traffic goes until 11p.m.For several seconds while the object was pretty near from my building i could see clearly a rectangle object with four white immobile lights in the corners, and two red flashing lights on the bottom, these two red lights flashing different from each other. The object made no-sound, it was flying in low altitude, it was smaller and fasten than an airplane. It appears in east and went west, and i observed that thing until it disappears in the horizon.I tried to film it but unfortunatly i couldnt, i was in shock.
