On the morning of Wednesday, 30 May 2007, a Missouri Air National Guard F-15 pilot ejected safely from his aircraft just before it crashed during a training mission in rural Knox county, Indiana. The plane went down just before 11 am EDT south of Vincennes, near the Illinois border, as it conducted standard training maneuvers, according to a release from the National Guard. Investigators said the plane was flying at about 20,000 feet prior to the crash. The pilot had been with the 131st Fighter Wing for 12 years and was highly experienced, officials said. The unit had most recently enforced no-fly zones in Iraq. This crash decreased the 131st's aircraft strength from 20 to 19.
