As long as BN is on charge, airworthy(!), and has a job to do, no way is she a museum piece. However, come the time when that is no longer the case, she most certainly should be. Commitment to that effect should be made now, for the historic record would point to her being struck off and used for fire fighting training, etc, or merely sold for scrap. As has been said her rightful place is surely the RAF museum, and that intention needs to be made clear ASAP. Not every preservation should be down to private individuals. We all have a debt of honour in the case of Bravo November, and her brave crews, and she should be preserved to witness that debt.
