It's always difficult commemorating accident victims on the current live operation, as it can be unnerving to certain passengers, however well meaning. The WW2 stairway accident at Bethnal Green, London, which is regularly portrayed as an Underground railway accident, but took place years before the stairway in question was incorporated into a railway station, has caused all sorts of differences between those remembering the incident and the current rail operators.
None of us would be unnerved here, and the aircraft is indeed appropriate, but the comments from the commercial team would be relevant as well. Can the George Cross, now in possession of BA's museum, be mounted in the flight deck ?
