Those of you who wear spectacles know that anti-reflective coating is a must.
Without it, the glass reflects so much it's darn near useless.
Er... sorry about the reflections in this picture - the glass is, er, not coated internally....
This is the view that greets you when you emerge from the lift...
Foreground : HMS Warrior
Middleground : HMS Victory in dry dock
Background : Portsdown Hill - the white peaks on the horizon are a model of a ship's superstructure, used for testing radar.
