Fourteen U.S. Air Force F-16 Fighting Falcon aircraft assigned to the 31st Fighter Wing at Aviano Air Base, Italy, are lined up on the ramp at Monte Real Air Base, Portugal, Feb. 10, 2014. The aircraft were parked in the center of the flight line to protect them from overhanging foliage and debris during a storm that struck the area the day before. Aviano-based pilots and maintainers were deployed to Portugal to participate in exercise Real Thaw 2014. Real Thaw is an annual exercise hosted by Portugal to develop interoperability for contingency operations between Portugal, European partner nations and the U.S. Air Force.
