Reading this warning

Hazardous operations: NGA's heading for activities that make an area dangerous — most often rocket launches, space debris and weapons firings, and some open-ended danger areas.

CANCEL THIS MSG: The warning's own expiry: a line telling the reader when the message cancels itself.
