The one in the Museum of Flight Seattle was roaded all the way from Toronto to New York State for restoration, and then on to Seattle. A journey of around 3,000 miles.

They were only there for a couple of years in the early-90s, before flying operations at Alconbury closed down in early 1995.

The based King Air aircraft left about 10 years ago

Brooklands does have a long term plan to cover their aircraft with a ‘wing’ roof. Concorde, VC10, Vanguard, Viscount, 1-11 and the Viking do comprise a sizable ‘civil collection.’
mmitch.

As does the Museum of Flight in Seattle, who plan to put a canopy over their outside collection of large airliners.

The Australian Beaufighter restoration is being done by HARS at Albion Park, NSW

…..some biggish ( British) historic civilian aircraft…….some which might in the meantime be flown in to Wyton (also apparently ceasing flying and conceivably not needing its hangars) if necessary, as a holding exercise.

None of the Duxford airliners are in any state to be flown again. Ever.

Would a museum consisting of nothing but busses with wings be commercially viable? I would very much doubt it, even with a Concorde as a centrepiece.

They stopped adding to the collection about 20 years ago, so there are no examples of the BAe 146, Jetstream, Vanguard, HS 748 or BAe ATP in the collection.

Walter Mitty appears to be alive and well.
