On 19 March 1939 the official opening of the airfield was marked by a large celebration, involving a parade from the center of Erlensee to the front gate, and a festival with an air show which saw 25,000 civilian attendees.

From the middle of 1944 until the Americans succeeded in crossing the Rhine, two successive groups of Junkers Ju 88 Nightfighters, the I/NJG 4 then III/NJG4, were stationed at Langendiebach.

Once the Americans had crossed the Rhine River, these elements of the Nachtjagdgeschwader 4 (NJG 4) were withdrawn to North Eastern Germany.

These succeeded in leading low-flying aircraft astray on many occasions, but could not prevent the comprehensive destruction inflicted upon Langendiebach by war's end.

The buildings and facilities of the air base were assessed as 20% destroyed, and the severely pockmarked runway as totally unserviceable.

All US Army assets in the Hanau Military Community were officially returned to the local government in 2008, and the MilCom was deactivated.

Fire brigades from all over the whole Main Kinzig District and from Frankfurt could not prevent the total destruction of the historic building.
