I did this on Friday (Cycled out from Brighton to start at Devils Dyke)…I actually forgot the airshow was on until found it online the night before.
First sight I got of an aircraft was when I was in this little valley on a farm road between wheat fields and this single Spitfire just went across…could have been 1940. Was on the very top when 2 spitfires and a Lancaster grouped to fly in and skimmed over me…unforgetable sight.
TBH I only really started to see the airplanes properly when I was pretty close to the finish though and would say it was best to be in town. Very busy though and dragging the bike through the crowds was diffcult. Good display by an orange and black F-16 though.
Have a great day 😀
