Hello Clay. The CONTECH staff had no relationship with airport personel and have no specific contact information. They did however supply information for the consulting engineer who designed the Manchester Airport dentention system in New Hampshire which is listed below. I will contact Dave McNamara Monday in an effort to glean the name of an appropriate airport official. Fay Spofford and Thorndike Bedford, NH Contact: Dave McNamara, P.E.
