I've no idea how long the current management has been in place but I'm certainly prepared to believe they, individually or collectively, have no interest in aviation.
When we last visited the Science Museum in London, neither of us having been since schooldays, we were really looking forward to what we remembered as an Aladdin's cave of exhibits and, particularly in my case, the historic artefacts in the aviation gallery.
What we got was an "experience" solely designed for children with "press here to read/find out" etc. and the aviation gallery closed every hour for 20 minutes or so to give some sort of children's show, with a presenter.
We left after about an hour and have no plans to return.
Open Wroughton and we'll be there very, very quickly.
