I went up on Beachy Head last year for the show, and you miss a lot of the display but a lot of the aircraft, come in from Shoreham along the coast and hold whilst waiting to display. Then on there departure they treat us to a nice topside. And last year the Belgian F-16 began and finished his display right in front of us with a nice topside pass.
Not to mention the Red Arrows who treated us to some amazing flypasts. All my pictures were taken just by the Lighthouse at Beachy Head on the cliffs, i parked right by the Beachy Head pub.
