The flight data recorders (FDR) were decoded by Kazakhstan Airlines and Saudia under the supervision of air crash investigators in Moscow and Farnborough, England, respectively.
[9] Indian air controllers also complained that the Kazakhstani pilots sometimes confused their calculations because they are accustomed to using metre altitudes and kilometre distances, while most other countries use feet and nautical miles, respectively, for aerial navigation.
Instead, they concluded – from the Kazakhstani plane's misleading flight data records – that the aircraft had descended while their pilots were battling turbulence inside a bank of cumulus clouds.
[24] As of 2021[update], there is an ongoing effort by the Charkhi Dadri district administration to develop a memorial honoring the victims of the mid-air collision.
