In 2005, the Taiwan government provided emails to Dhar that it has no records of a plane crash during the period of 14 August to 25 October 1945, at the old Matsuyama Airport (now Taipei Domestic Airport). These records played a major role in the final assertion of Mukherjee Commission about the implausibility of Bose dying from an air crash. Historian Sugata Bose has rejected the analysis in light of the fact that the region and the airport was under Japanese occupation until 1946 and it was around 1949 when the Taiwaniese government finally consolidated itself.
