Mesrarce @ ORTECTIVE The objective of Project 1.1 in participation in to document the propagation of the blaet wave from a INSTRUMENTATION The instrumentation used was the BRL self recording pt and q gages. The pt rages were mounted fluah with the surface of the ground and the q gaves vere mounted with the centerline of tre axis 3 feet above the surface.
