After investigating the incident for more than a year, the Air Force released its crash report in December 2011 that said that while [Capt. Jeff] Haney likely suffered a "sense similar to suffocation" right before he died, he was still to blame for the crash for being too distracted to fly the plane properly.
The new IG report, the result of the first major crash investigation review undertaken by the Inspector General since the mid-1990s, says that the Air Force's conclusions are at times contradictory, incomplete or "not supported by the facts." In response, the Air Force said it convened its own special task force to review its investigation, and the task force found the original conclusions were adequately supported.
Haney's family has been aggressive in pushing the Pentagon to investigate the crash, citing many pilot reports of problems with oxygen delivery in the F-22.
