Sergey Burdin's previous military experience in the Russian Air Force gives him the edge in that he has 'first-hand' experience of the aircraft and its operation. Additionally, Burdin has recently compiled a comprehensive record of accidents and crashes involving the Tu-22 during its service life. This includes full descriptions of the circumstances and causes of the accidents, with blame apportioned to the 'guilty party/parties' in each case. This is quite unusual for Russian military aircraft accidents.
