I'm glad there were no injuries. I've been going to airshows for the last 30 years and seen the Thunderbird, Blue Angles and Snowbirds more times than I can remember.
Theire acts can be repetitive after you've seen them a few times but for a 'first time' viewer they can be very exciting, and that's there goal.
Anymore I just enjoy watching the crowd react to the show and marvel each time at how they move a 30,000 lb aircraft through the sky.
