Well, it seems I have spoken just a moment too soon. At least no one was hurt, apparently. There’s not a lot of news on the accident, but it seems as though it was the design and a rigged piece of gear that failed.
In Lages, Brazil, a truss component of a stage design fell last night onto the stage deck – from the article at Porto Menina:
Lages / SC - The Central Committee Organizing (CCO) of the 25th National Party Pinion reports that the unforeseen event that occurred yesterday afternoon Tuesday (27) at about 16:30, involving the Stage National solved ASAP not affecting the show Alexandre Pires and SPC.
The problem was the breaking of a part of the column structure lighting, when changing the map of light needed to show the SPC, remembering that each show has a different map.
Also said that the show just happened in To Thwart National Stage from 22:30, as scheduled.
More news as I can find it on this accident — but I guess we have to count one for the disaster pile.
