Upsidedown C-130 at Stockbridge Research Facility

The Stockbridge Research Facility is located atop a 2,300-foot hill 23 miles southwest of Rome, N.Y. in Madison County. Larger, strategic-type aircraft such as KC-135s, C-130s, B-52s and sections of a B-1B are tested at this site. The aircraft are mounted on a very large turntable and rotated as a special measurement probe rides up a 200-foot track that forms an arc over the turntable and airframe. Measurement data is collected over a complete hemisphere in this manner. The airframe is then flipped over and the measurement process repeated to collect data on the other hemisphere, thus providing antenna data over a complete, 360-degree sphere around the aircraft.
