Notice about Landing Sites: INFO MAY NOT BE ACCURATE
Choice of landing sites is a pilot's personal responsibility.

The landing attribute "L" has been appended to a few of the control points that MAY have been landable in the past, but they may not be landable any longer.
Pilots must decide for themselves which control points may be landable for them, and then add or delete attributes as appropriate.
