Mysterious diamond-shaped UFO seen from aircraft over Texas

The footage was sent by a witness, identified as Steve, who works as a maintenance officer with an American corporate jet fleet, according to Secureteam10.
Steve captured the video through a plane window while flying in an aircraft over east Texas at an altitude of 43,000 feet and shared the footage with the Secureteam10.
The witness  began filming the UFO, flying level with his aircraft, at about 5:54 pm. It disappeared at about 6:08 pm, nearly 15 minutes after it appeared. The object appeared to be diamond-shaped, consisting of two cone-shaped structures: one pointing up and the other pointing down. The date of the sighting is uncertain.
