An interdictor is a type of attack aircraft that operates far behind enemy lines, with the express intent of interdicting the enemy's military targets, most notably those involved in logistics. The interdiction prevents or delays enemy forces and supplies from reaching the battlefront. The term has generally fallen from use. The strike fighter is a closely related concept, but puts more emphasis on air-to-air combat capabilities as a multirole combat aircraft. Larger versions of the interdictor concept are generally referred to as penetrators.
In the post-war era, the RAF introduced interdictor variants of their English Electric Canberra jet bomber, the aircraft being available as the strategic bombing role had been taken over by the new V bombers. An early interdictor was the F-111, an aircraft able to operate at long distances from its base. The Panavia Tornado was built for a similar purpose, although operating over shorter ranges in the European theatre. The Soviet Sukhoi Su-24/Sukhoi Su-34, Chinese Xian JH-7 and the aborted British TSR-2 are similar interdictor designs.
Interdictor is the name of a LiveJournal blog that documented the effects of Hurricane Katrina in New Orleans during and following the destruction. It is operated by Michael Barnett. At the time he was an employee of Directnic.com, an internet services company on the 10th and 11th floors of an office building in downtown New Orleans at 650 Poydras Avenue, which he referred to as "Outpost Crystal" (after Barnett's fiancée, Crystal Coleman). Daniel Gifford, another employee of directNIC.com, also contributed many articles to the blog. In the early aftermath of the hurricane and flooding, it was one of the few reliable communications links between downtown New Orleans and the rest of the world.
Operating on a diesel generator when power was lost, Barnett and fellow bloggers provided a continuous stream of reports of what was actually happening and, through webcams, live video feeds, and thousands of high resolution pictures, gave the rest of the world a chance to see the looting and destruction firsthand before the rest of the media arrived on the scene. Using Internet Relay Chat and instant messaging they kept in constant contact with the outside world.
