The delta wing of the Tupolev Tu-144LL supersonic flying laboratory is evident in this view from underneath the aircraft during a 1998 test flight at the Zhukovsky Air Development Center near Moscow, Russia. 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 / NASA› TU-144LL Project Description
