Regarding the other pic with the Horsa and the lone trooper I would suggest that the tree line we see is the main road i.e. the western boundary of DZ "A" - the road was tree-lined.
Alex, Great catch on Pte. Brownjohn. Some of his photos can be seen on the 1st Canadian Parachute Battalion Virtual Museum. Overall, though darker, the photos are slightly better. Regards ...
Looks like a wing to the right in photo of both men. I lightened up Pte. Brownjohn's photo of DZ 'A' using a touch of gamma correct. The Axehead is seen to right before the arrival of gliders. Regards ...
Yo, Are the men seen first and third from right in photo below Glider Pilots? Possibly a still from a clip and the only acknowledgement of Sgt, Bill Lawrie's Varsity camera work found so far. The IWM listing for his Varsity footage, A70 278-6, though never available for viewing, appears to have been scrubbed. Lawrie may have been the cameraman to have caught the flaming Dakota passing at low altitude over DZ 'A' as viewed by Paratroopers sorting themselves out on the ground? Regards ...
Yes, they are glider pilots. I ordered a print of the photo in the 90s because in the background it shows the pub where many days of my misspent youth were enhanced by freshly drawn Pilsener beer...
