darn! I forgot about concord, they shouldn't be allowed because they are out of service, but anyway as you said, lets make it a fun one. 9/10 for the concordy.
One day, we were going back to our home from england, in 2007, we got stuck on the ruddy M25 and missed our turkish airlines flight, we were gonna spend the summer holidays in turkey like always, you see. So the check-in closed, we went to the Turkish Airlines booth and they said we needed to pay a fine because we missed our plane, and whats more, our ticket had been sold to someone else! There were 10 other people in the same situation and we were all shouting at the people in the booth and they were being deafened. Soon we had to pay some more money to get another ticket and missed half of our holiday before heading of to France.
Go on, give this plane a 1/10!
