Constructive critique
Sadly, it isn't on of the better spotting videos I've ever seen and as someone else has also pointed out, maybe PPRuNe isn't the website for posting this kind of video even though we have a Spotters Corner section.
1. Get a tripod or monopole for ground shots. These aint much cop for take offs or landings though.
2. Beware, when shooting through a mesh fence with an autofocus camera, the focus will nearly always focus on the fence, not the subject matter (see your BY 757 for example)
Keep trying, the only way is up!
