More on the TU-144!

Apparently NASA has been conducting some joint experiments using an old TU-144. Very interesting..

See if you can spot the differences!

Boeing also had two VERY similar designs, one was a bomber, and the other was a Super Sonic Transport (both considered two of Boeing’s greatest fail- ures):

Imitation is the sincerest form of flattery..
