in the UK there's no security prior to entering a terminal
In Domodedovo there are security facilities at any entrance door. In the past there was no way to enter without sending your luggage (check-in + carry-on) and coat through the x-ray and walking through the magnetic detector. Since 2009 they are no longer in use... Instead they have installed the full body scanners in the new security area. Where by the way they already succeded to pick my wallet. Domodedowo is a security nightmare in the public areas, there are so many people around which are not passengers, the meet & greet area is always crowded, full of people making their living as unlicencenced taxi drivers with their private car.
