Crash Relic: Access Hatch Do217 Wartungsklappe
This is an access hatch from a WWII Luftwaffe Dornier Do217 twin-engine Medium Bomber recovered from its crash site in Poland. The illustration from its parts manual shows that it provided access to the wing tie-downs, intended to secure the aircraft to its parking stand on the airfield.
Measures ~ 5 inches in diameter. The metal clearly shows the effect of climate exposure and its age.
