All 16 injured students are out of the hospital as state spokesman says public school stages may not legally require inspectionThe superintendent of an Indiana school district where a stage collapsed, injuring 16 high school students when they plunged into an orchestra pit, said Friday that the section that gave way was only a few years old, but it is unclear whether it was ever subject to inspection.The uncertainty surrounding the regulation of the orchestra pit cover that collapsed during Thursday’s finale of a musical at Westfield high school, 20 miles north of Indianapolis, is reminiscent of questions that arose in 2011, when heavy winds toppled stage rigging onto fans awaiting a performance by country duo Sugarland at the Indiana State Fair.
