See AB regularly and from distance it doesn't look too bad.
If it is in a bad state that would be odd.
I used to volunteer on the Intrepid in NYC and have some knowledge of AD.
All the former BA Concordes are all still owned by BA to prevent them been put back in the air as are all the Air France ones. You have to sign an agreement when you get one to say you will keep it looking good and in an approved (by BA) paint scheme.
The engines from AD are in a hangar at JFK and Captain Leslie Scott the pilot who holds the west-east record regularly visits the Intrepid as he lives in the NYC area.
