Funny business?

Late last evening three helicopters circled our house a few times.  The big Coastguard landed close by for a few minutes.  An Air Ambulance went off down towards the A19 (no accidents recorded) and a black smaller helicopter joined in.  No idea what it was, nor do the local website experts (though a few couldn't help  themselves from saying they didn't know what was happening but they hoped they were alright).

Nothing on the local news this morning that I could see.  All very mysterious.
