Gibraltar (LXGB) - interesting approach due to wind from the rock and approach over the sea.
London City (EGCY) - 5 degree glide slope
err... cant think of anymore.
oh....i was playing on flight sim, cant remember the name but on 2004 in Canada there is an airport which is below the sea (!!! I know) basically water pours like a waterfall around it!
Very odd. Think it was in BC somewhere.
Good luck,
