Hard to say how many shows will be cancelled. If you recall about 2-3 years ago, the Thunderbirds had a minor incident at Macdill AFB
in Tampa when two of the four "diamond" aircraft touched just after takeoff. The pilot deemed at fault was removed from the team and replaced by a recently departed member of the team. The result was about two months of cancelled shows. Coincidentally, the team was returned to show status just in time to make their annual Air Force Academy graduation fly-by!
That suspension was the result of pilot error, so it's understandable that it took time to bring the former pilot back to "show ready". Because this most recent accident looks like it might be attributed to a mechanical failure, it's reasonable to think, because the team has about 10-11 jets, that the team could be flying again soon.
BTW -- The desert crash WAS the Thunderbirds. The only Blue Angels accident I can recall was about 4 years ago near Moody AFB
during a practice for the next day's show. Unfortunately, that pilot was killed.
