What the?!

If you don't know, i live in Porthleven - a small fishing village 2 miles from RNAS Culdrose. From about 8:00pm there has been 2 Sea Kings from 771 squadron flying VERY low over the village. As i write this (11:00pm) one is hovering over the harbour, the other is above some field a short distance away. As it is dark they are using bright spotlights. 771 is one of the SAR squadrons at Culdrose but they are not searching the coast, they are searching the village, nearby forest and hills... any ideas what this could be about? They are searching in the fasion of a police chopper looking for a suspect. I'm used to the choppers buzzing about but this is very out of the ordinary.
Here is a couple of shots i got... excuse the quality - i had to borrow my brothers camera.




So any idea whats going on here?
