With the outbreak of WWII and the imminent fall of Paris, Bugatti had the aircraft disassembled and hidden on his estate. Bugatti died in 1947, having never resumed work on it.
The aircraft remained in storage throughout World War II. It was sold several times, and its twin Bugatti 50P engines were removed for automotive restorations. In 1971 a restoration effort was started. The aircraft was stored by the National Museum of the United States Air Force, then transferred to the EAA Airventure Museumcollection where restoration was completed, and it remains on static display.
