Air view of Skardu 2011
Looks like it was taken from a helicopter.
Very mountainous area. Great opportunities for terrain masking.
The approach is a bit cozy, but there's plenty of room for a 777.
I don't see a single hangar on the property, however -- nothing to stash the plane in and hide it from view.
