In fairness to the public, the two companies involved in producing Concorde have each changed names 3+ times after merging with other major aircraft and industrial concerns, and are each now fading memories as part of the two largest European aerospace & defense conglomerates.

I'd actually wager a significant portion of the population would correctly say Airbus, but for the wrong reasons - it's the only French aerospace company they can think of.

I did a straw poll among some friends and got a lot of "I don't know what that is. Do you mean the grape?"
