Federal regulators are calling for stricter requirements to fly hot air balloons after a crash near Lockhart last year that killed all 16 people aboard.

The National Transportation Safety Board on Tuesday released findings and recommendations of its investigation into the July 30 accident in which a balloon operated by the Heart of Texas Balloon Ride company struck high-voltage power lines about 30 miles south of Austin.
