In the 1st and especially the 2nd World War, several aircraft crashed in Eastern Flevoland. Many of these aircraft were found and salvaged during the draining of the polder. In 2008 the idea arose to register and describe these aircraft and to mark the locations with a memorial pole.

There are a total of 19 memorial poles in Eastern Flevoland, which together form the Crash Pole Route. This is to realize a lasting memory of the Airgunners and to make visible a piece of history that revealed itself during Prohibition.
