OPSEC my ar$e!!! Who the F&*^ are you?
NOTAMs are full of all the info you need (Including the Oil Rig Name and location and the formation of helo's and where they came from) and a quick Google comes up for Newton with photos and the gen you need for Newton and SF Support Ops!!!!
You only have to sit on a cliff top down in the SW and watch Chinooks with 'chaps' fast roping down on Newton to realise what they are up to! Or to watch them in full view of Devonport and Plymouth Sound wandering around on deck and timing themselves jumping in their ribs attached to the hull!! If you do a quick Google yourself you won't get ya ar$e in a twist!!
