KATE ARCHER KENT

A top secret missile strike over Baghdad -- the first mission of Operation Desert Storm in 1991 -- will be the focus of a symposium Saturday.

Commentator Gary Joiner marks the 40th anniversary of a milestone in military aviation. Operation Linebacker II was an 11-day assault on the North Vietnamese capital and surrounding area in Dec. 1972 that forced the enemy back to the negotiating table.
