Re: Which mystery European airline other than VS bought 15 Boom XB-1?

Concorde was much less safe than current airliners, people just didn't know it. On top of the crash it had many lucky breaks. It could never be certified today. Today's airliners aren't supersonic; SST aircraft have to deal with a large number of challenges that are inherently far risker at that sp...
