You linked a retracted paper full of objectively incorrect data as listed in the retraction.
Military planes and passenger planes fly at different speeds and altitudes.
This may come as a shock, but the temperature and humidity at ground level does not reflect the temperature and humidity experienced by planes during flight.
The author disputed the retraction which seems politically motivated.
