I love the airshow! In the past, I've gone on both days. One day with family, and the other with friends. I've never been as an enthusiast before; nor have I noticed any bus enthusiasts taking photos (I must be blind!). Do hope to include a few photos in this year though - if I can get there early enough so as to avoid masses of people getting in-shot.
I think last year the airshow collided with the North Tyneside Music event hosted on the big field next to South Shields beach, so I may have only gone the once last year. Really can't remember if that was the reason, but something happened for me to only go the once then.
