The Tupolev Tu-144LL supersonic flying laboratory touches down at the Zhukovsky Air Development Center near Moscow, Russia, following a 1997 test 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.July 1997NASA Photo / NASA/IBP› TU-144LL Project Description
