I drive Adana to Mersin almost everyday due to my job. During my travel, I have seen an oval dark and a big object (bigger than a passenger aircraft) flying faster than a plane. The weather was wet and the sky was cloudy. The object was flying through the clouds from the north to the south , so I was able to see it with short durations (every 2 to 5 seconds) I stoped the car and tried to take a video. However, the object was disappeared in the dark clouds. The object was dark colored without lights. It does not look like an military or a passenger aircraft. I am very familiar this kind of aircrafts. This object was completely different.
