An Army helicopter landed on the University of South Carolina’s downtown Columbia campus Thursday morning.
The landing took place on the Blatt PE sports field as part of the school’s National Engineers Week celebration.
It was intended to highlight the work USC engineers have done to make military helicopters more efficient.
Engineers at the school have installed sensors throughout Army Apache helicopters that allow the military to know when maintenance is needed.
USC researchers say the military can now wait to make repairs only when they’re necessary.
Previously, the military would do repair work based on the amount of use of the helicopter or its length of service.
The Army says the new sensors have saved $45 million a year in parts alone.
A second landing is planned for Saturday morning at 9:30 a.m.
