One person was killed and four others injured Tuesday when a helicopter crashed into a lake in the western Mexican state of Michoacan, authorities said.
The Bell 407 chopper went down after striking a cable of one of the zip lines that cross Lake Zirahuen, the state Attorney General's Office said.
Normally used as an air ambulance, the helicopter's mission on Tuesday was to capture video footage of the lake for use on a television program.
The Michoacan state government lent its aircraft to the effort under an agreement with Television Azteca to promote Lake Zirahuen as a tourist destination on the network's "La Academia" reality show about budding musical artists, the AG's office said.
The helicopter was carrying a pilot, co-pilot and three employees of the Azteca 360 Management production company.
First responders rescued the crew and two cameramen, but producer Daniel Segundo Martinez was killed in the crash.
The four injured survivors were taken to a hospital in Morelia, the state capital, about 70 kilometers (43 miles) from the lake, the Michoacan AG's office said. EFE
