After the act on US troops overflight, transit passage and stay on Bulgarian territory is implemented, the US military aircraft will use the civil airports, Defense Minister Svinarov said before the regular weekly meeting of the Bulgarian Government. Four to five airports will be used for that purpose. Two or three of them will be military ones. Svinarov added that special schedules will be prepared for the US airplanes. Also temporary bases will be set up near the airports. So far, there have not been concrete demands on behalf of the United States, the Defense Minister reiterated.
