Some of the volunteers are incredible! Lots of interesting background stories, and if you're (un?)lucky, you'll get the guy I did who made it sound like the fatal demise of the Concorde was a certainty, only a matter of time until something terrible happened. OK, no biggie, except when you're standing 10 feet away from it, and it's as real as any other plane you've ever traveled in.
