This 4 inch diamemter embroidered patch was used by the flight crews of NASA's approach and landing test program for the space shuttle in 1977.
The first orbiter spacecraft, Enterprise (OV-101), was rolled out at Rockwell International's Palmdale, California, assembly facility on Sept. 17, 1976. On Jan. 31, 1977, it was transported 36 miles overland from Rockwell's assembly facility to NASA's Dryden Flight Research Facility at Edwards Air Force Base for the approach and landing test (ALT) program.
