SAN ANTONIO—State pilots have flown a $7.4 million high-altitude spy plane from San Antonio to Fort Stockton.

The San Antonio Express News reports ( http://bit.ly/1gxdKZW) that the Swiss-made aircraft was flown Friday by Texas Department of Public Safety pilots. It was equipped with $1 million worth of surveillance cameras.

The flight took an hour and 17 minutes at an altitude of 16,000 feet.

A DPS spokesman said the aircraft assisted ground personnel in Terrell County, bordering Mexico, in locating two subjects suspected of firing a weapon during an incident with law enforcement earlier Friday.

The aircraft has a pressurized cabin, allowing it to fly up to 30,000 feet high.

DPS purposed the plane in 2012 for surveillance and to assist U.S.-Mexico border operations. It's also been used to support emergency situations.
