B-17 units in the Mediterranean Theater of Operations operated from the following Airfields:    Most combat airfields were temporary wartime facilities quickly constructed with pierced-steel planking runways and parking areas, with tents used for personnel quarters and a few wooden buildings used for operations. In Tunisia and Italy, some captured German Luftwaffe or Italian Air Force (Regia Aeronautica) airfields were repaired and placed into service. Today, most show little evidence of their existence other than some faint outlines in agricultural fields.
