But "close the A27" for the greater part of two days? Does anyone making this preposterous suggestion actually realise what this would do to traffic in this area?
In the aftermath of the tragic accident at Shoreham, the local traffic was diverted around the closed A27 junction for quite some time. Many roads are closed for events and the locals have to pre-plan their movements and deal with it the best they can. Every summer, the London to Surrey Hills and back cycling event closes many roads for most of the weekend. This mitigates the risk to both the spectators and the riders during the event.
Why not? Do the same for airshows, to mitigate the risk to passing traffic on a road close to the planned flight path.
