I know the russian TU-144 did fly one time to Paris to be presented here. But did our Concorde also travel to Russia in that time as well?
I could not find any information for that.
Tu-144 was briefly used and only inside USSR. Concorde was used btw Europe and USA.
Both programs failed. Supersonic aircraft are expensive and not people trust the technology. Standard planes have became well proven plateforms with very little accident.
