Hindsight: Perhaps the future of air displays will lie in the name, 'Shoreham by Sea'.
Springing to mind, Bournemouth, Dawlish, Plymouth, W-S-M, Clacton, Southend on Sea, in fact any of the coastal resorts around the country could be future locations.
As an aside, I would have thought that access would be generally be better for 'resorts' than that of the normal airfield sites, usually accessed by country roads.
RIP, a sad day
