USAF McDonnell Douglas KC-10A Extender (85-0029) leaves SCL as RCH071. 

This departure was maybe the second to last time the KC10 departs from Santiago as they will be decommissioned and gradually replaced by the KC-46.
The last supposed take off from SCL came after a week as they returned to refuel the raptors on their way back to the US.
Hope you like it and enjoy watching it as much as I did.
