The Tupolev Tu-144LL supersonic flying laboratory shows off its sleek lines in a low-level pass over the Zhukovsky Air Development Center near Moscow, Russia, on a 1998 research flight. Two NASA research pilots – Robert Rivers of NASA Langley and Gordon Fullerton of NASA Dryden – assessed the Tu-144LL’s handling qualities at subsonic and supersonic speeds during the first three flights in September, 1998. The follow-on series concluded after four data-collection flights in the spring of 1999.September 1998NASA Photo / Jim Ross› TU-144LL Project Description
