Thanks for the responses.
So two separate new security areas both at the check in level 2 - that's re-assuring.
IIRC the original T2 security area was on Level 2 before it had its last major make-over and moved upstairs.
Fingers crossed for those 3D scanners. It would barely make sense to install 2D only to have to retrofit 3D soon afterwards. For anyone that's already used them it's like a breath of fresh air and such a far cry (pun intended) from all the shouting and intimidation that goes on at most airports (not just MAN)
