How many Military Planes was used during World War 2?

The numbers are a bit difficult due to some Military Aircraft being in Operation whereas, some were not in Operation. However, in past decade or two, there has been some research into this related topic and It has been proclaimed there to be between 110,000 - 150,000 Aircraft (Operational and Non-Operational). Most people agree with this and It has been closely estimated of being about 136,000 Aircraft. About 14,0000 were non Operation Aircraft.
