Possible BAC Concorde Problem?

There is a player in R4 who has very young Concordes for the date of the game world.

These Concordes, in August of 2014, are aged at 0.50 years. Since the aircraft went out of production in 2003, this seems a bit odd. There may be an explanation and I will try to ask the player about this. I'm just reporting it because it's odd.
