Just wondering what the ceiling requirements are for each show are. Thanks

Approx; High: 8,000ft and 3sm, Low: 3,500ft and 3sm, Flat: 1,500ft and 3sm. Sometimes the ceilings are fluctuating though and the Thunderbirds will shift mid-show from vertical stuff to low stuff and back. If the visibility is lower, they'll usually fly a series of flat passes with the Delta, not a demo...
