Mainly during World War II, several aircraft have crashed in Oostelijk Flevoland. During the reclamation of the polder, many of these aircraft were found and salvaged. In 2008, the 4th of May Remembrance Foundation Dronten got the idea to register and describe these aircraft and mark the crash locations with a memorial pole. This in order to implement a lasting reminder of the Airgunners and at the same time to reveal a piece of history that was discovered during the reclamation.

The disclosure of the first memorial pole took place on the 29th of April and was made by Mr. Gerrit Zwanenburg (former salvage officer), Rutger Kuiper (former National Office IJsselmeerpolders and as such, involved in the depopulation of the first airplane wrecks) and one of the longest visiting Airgunners, Ron Powers.

Memorial pole #001 was the first in a series of 16 poles, placed by the 4th of May Remembrance Foundation Dronten in 2011.

During the search for the crash sites, many stories became known. These stories will be placed on this website later.

For this project, the 4th of May Remembrance Foundation Dronten has had the kind co-operation of Flevolandschap management and the following sponsors: National Postcode Lottery, the Prince Bernhard Fund, Rabobank Flevoland, HAZO Technology Lelystad (creator of the poles) and Van Werven (taking care of the placement of the poles).

Other counties expressed their interest to participate in this project, also the "Nieuw Land Erfgoedcentrum" and the Archaeological Group Netherlands are interested.

The working group "Ongeland" records all crash sites in Flevoland and marks them.
