A small plane crash in the northeast region of Kansas last week killed four people and injured one other. All five people were connected to Oral Roberts University and were traveling to a Christian youth rally at the time of the crash.

According to officials with the National Transportation Safety Board, the Cessna-401 went down on Friday afternoon and burst into flames upon striking the ground.

The small plane radioed air traffic control to get permission to lower to a different altitude, but once this was the last communication made from the plane. A 22-year-old passenger is currently recovering from critical injuries in the University of Kansas Medical Center, but four passengers, all in their 20s, were killed.
