The U.S. Air Force, NASA, and Grumman aircraft company said they had reached the mid-point of the X-29 vortex flow control (VFC) program at Edwards Air Force Base in California, producing yaw rates of up to 20 degrees. The use of VCF to yaw the aircraft while at a high angle-of-attack is an aviation first according to Col. William Gotcher, X-29 program manager. (Flight International, Aug 19-25/92)
