The Polish Aviation Museum is in Kraków, Poland. It is located at the site of the no-longer functional Kraków-Rakowice-Czyżyny Airport.
This airfield, established by Austria-Hungary in 1912, is one of the oldest in the world.
It has an amazing collection of Ex-Soviet MIG jets in the world. A must see for any pilot- photographer.
