Wind-tunnel tests of 4% scale models of the space shuttle orbiter had begun at Air Force Systems Command's Arnold Engineering Development Center, the Air Force announced. The tests of heat buildup on the forward half of the orbiter during the critical period of reentry and at other points in the flight trajectory were scheduled to continue through the remainder of the year. The 4% model, the fourth size to be tested in the AEDC tunnels, reflected the latest design details on the forward half of the orbiter. (AFSC Release OIP 207.74)
