Nylon purchase tape lay stretched out across the flightline

Nylon purchase tape lay stretched out across the flightline after an engagement from an F-16 Fighting Falcon during certification of a newly replaced Aircraft arresting system at Davis-Monthan Air Force Base, Ariz., April 11, 2015. The tape’s elastic property stops an aircraft during emergencies involving brake failure, steering problems or other situations in which using the full length of the runway is not possible or safe.
