Boeing CH-47 Chinook

We normally see a Chinook fly over at least once a week but this week we had an extra treat. On Monday(27/3/2017) my wife came running down stairs shouting there's a Chinnok coming straight at us. I could hear that unmistakable sound and it was very loud. Apparently she was looking out our bedroom windw and it was coming straight at her. It flew extremely low over the house making everything shake. I had just enough time to catch it going over a neighbour's roof.

I assume that Chinooks fly VFR as there was a very low cloud base following an early mist. What made it more alarming for the wife was the nose down attitude.

This morning (30/3/2017) two more flew over but at normal height. However this evening we had two Apache's and what I think was a Super Puma. Must have been some exercises somewhere?

Just after I posted another two Apaches flew over. Will probably get more Chinooks tonight!

The evening got noisy again as another Chinook flew over, heading west at 23:19. This was followed by 2 Apache at 23:32, " Apache at 23:49 and a single Apache at 00:17 - all heading west. Probably more to come but I'm off to bed!

In the last 5 minutes we have had 3 Chinooks, 5 Apaches and 1 Super Puma. I assume returning from the other evenings trip.

The ones we see every week look to be one colour with no discernible markings, so I assume very toned down.

The MOD have released some good pictures and video which are on various websites.

I tried zooming into some of the pictures but could not read any identification though could be something on the side. Might be a "L" underneath. It is difficult to enough to see the RAF roundel.
