US Marines rescue their helicopter... with a bigger one

US Marines have rescued one of their helicopters after it made an emergency landing on a beach in Okinawa, Japan. The aircraft was airlifted back to base using an even bigger helicopter.

The US presence on Okinawa in southern Japan is a key part of the security alliance between the two countries. Their bases house about 26,000 US troops.

There are plans to relocate part of the operation to a less-populated area of the island, but many Okinawans want it removed altogether.
