YFR3 said Hardy filmed at Digue du Braek and that is near that lighthouse you see the landing plane pass.

I believe that lighthouse (or one like it) is also seen in the background past the grounded trawler.

In both cases they make it seem like those spots are clockwise along the beach from the middle of Dunkerque (to the right if facing the ocean).

I am still wondering if the plane's landing spot is meant to be around the same location where the grounded trawler was, and even if the Germans who caught Farrier could be the same ones who were shooting at the trawler for target practice.

Now I think about it... I've been to Dunkirk and both the trawler scene and Spitfire landing scene are mirrored. They're both filmed at the Digue du Break but in the film they're depicted as if they are at the right of the mole (seen from Dunkerque with eyes to the sea).

Maybe that spot west of Digue du Braek was most suitable for filming the dangerous dune-edged outskirts of town (and/or more suitable for landing a spitfire), but maybe shorefront homes to the east looked better for filming the earlier part of the glide?

The beaches east of Dunkerque , on the French-Belgian border near De Panne , were deserted as of 31 May 1940 by British troops who had been informed that no more vessels would come to pick them up. Sector 313 . This is where Tommy ( Fionn Whitehead ), Alex ( Harry Styles ) and Gibson ( Aneurin Barnard ) run aground in the film after the destroyer destroys and Farrier ( Tom Hardy ) places his Spitfire at the end of the film . These two scenes are filmed on the embankment of Braek, west of Dunkerque , but the assembly situates them well to the east of the city, at the limit of the perimeter of defense, near the German lines.

Original French:
Les plages situées à l'est de Dunkerque, à la frontière franco-belge, près de La Panne, ont bien été désertées à compter du 31 mai 1940 par les troupes britanniques qui avaient été informées que plus aucun bateau ne viendrait les chercher dans ce secteur313. C'est l'endroit où Tommy (Fionn Whitehead), Alex (Harry Styles) et Gibson (Aneurin Barnard) s'échouent dans le film après le torpillage du destroyer et où Farrier (Tom Hardy) pose son Spitfire à la fin du film. Ces deux scènes sont filmées sur la digue du Braek, à l'ouest de Dunkerque, mais le montage les situent bien à l'est de la ville, à la limite du périmètre de défense, près des lignes allemandes.

That's definitely the same location. It is said by Joshua Levine in the official book. It is supposed to be the Bray-Dunes / De Panne sector in the movie
