The report, as filed
There were indeed aircraft, but they weren't chasing. They are commercial aircraft, whose route passes over my house. Original report in Portuguese: Vi luzes no céu noturno e vi mesmo uma nave a pouca distância,movimentando-se de sul para leste.Não é a primeira vez. Havia aeronaves sim mas não perseguiam são aeronaves comerciais,cuja rota passa por cima da minha casa.
