747 from Offutt doing 'touch-and-go' landings at airport

Wondering what's been happening with the 747 landing at The Eastern Iowa Airport today? Don't worry -- it's just a drill.

The plane, from the Offutt Air Force Base near Omaha, Neb., was doing "touch-and-go" practice landings at the airport, according to the airport's Twitter feed.

The airport has been receiving "lots of calls" wondering what's happening, according to their Twitter updates.

"The E-4B serves as the National Airborne Operations Center for the president and secretary of defense. In case of national emergency or destruction of ground command control centers, the aircraft provides a highly survivable, command, control and communications center to direct U.S. forces, execute emergency war orders and coordinate actions by civil authorities."
