More than 150 children and staff are evacuated by helicopter from a summer camp in Missouri after a building collapses, according to reports from Australian outlets. The evacuations remove people from the camp area after emergency services respond to the collapse.

In addition to the larger group flown to safety, around 20 people are reported to be rescued from a campground area. The reports describe helicopter operations as the primary method of transport for those affected, indicating that ground access may be limited due to the incident and its aftermath.

The accounts focus on the scale of the evacuation and the number of people rescued on site, but they do not provide further details such as the exact location within Missouri, the cause of the collapse, or the extent of injuries. Authorities are not quoted in the provided summaries, and no official casualty figures beyond the reported evacuations and rescues are included. The situation is described as an active emergency response involving multiple rescue efforts.
