Concorde has a Tmo, not Vne.

I have no idea about emergency descents but the normal one is a
reasonably complex affair because of the temperature effect.

Basically, the aircraft needs to slow as it descends up (down?)
to about FL400-350 where I think it transfers to a constant IAS
of about 420kt.
