"Fatal Propeller Accident Blamed on Lack of Situational Awareness and Inadequate Training"

A California contractor, Stephanie Cosme, was killed after walking into a plane's moving propeller due to inadequate training, poor lighting, noisy conditions, and a rush to finish testing, according to a United States Air Force accident investigation report. The report found that Cosme was incorrectly instructed or trained on how to take telemetry readings and lost situational awareness while approaching the aircraft, with a clear lack of communication among the contractor test team and ground support personnel.
