A team from Culdrose Air Base has been sent to help victims of Typhoon Haiyan in the Philippines. They'll be giving aid using a Merlin MK 1 helicopter that's usually based near Helston.
The crew have been deployed since June, and now won't return till after Christmas.
They were taking part in counter-piracy operations before the Prime Minister sent them to help.
Five people have been rescued after their boat sank in stormy conditions off the Cornish coast. The RNLI and RNAS Culdrose search and rescue helicopter helped to rescue the crew from the sinking French fishing vessel off the Lizard around 1am this morning.
Two tankers also helped to shelter the boat while waiting for rescue.

"With stormy conditions out to sea, we needed to act quickly to help these five crew members try to stop the water coming into their boat. Unfortunately, the pumps could not cope and they had to get into their life craft. From there they were winched to safety. "Luckily none of the five were hurt or showing signs of hypothermia as they were all wearing survival suits. This undoubtedly aided their survival in what have been tricky conditions tonight."
