That Avro Arrow is a replica, as someone already commented. The only one in existence, as I understand. Beautiful, though, and really big! Someone in the Arrow team was talking to my coworkers and I for a good twenty minutes about the replica project. Looks like it's destined for a hanger at Pearson for a while.
TorontoTrekker, my company was just an exhibitor, and had nothing to do with the Arrow. We were lucky, though, because our booth was maybe a couple hundred feet from her. And we left through the Arrow tent every day.
