...and the second post to conclude the photos and ask a question:
Concorde cockpit (through hazy perspex screen)
TU-144 cockpit (also through hazy perspex screen)
A sign that made me chuckle
I hope that these pictures were of interest and can spark some further discussion in this amazing thread. If I can have the temerity to start the ball rolling with a TU-144 question, I was intrigued to notice the following tiny vane situated on the fuselage base between engines 2 and 3. Closer inspection revealed an adjacent hole, perhaps indicating pressure measurement? Anyway, ideas or proven fact welcome!
