The success of an un-manned military helicopter supply program developed by Lockheed Martin is being celebrated in Owego.

The K-Max chopper that was designed to deliver food and supplies in combat zones, reducing danger to personnel that would otherwise have to go into those zones to resupply troops,  was only supposed by used for a few months, but the mission lasted close to three years.

The drone returned to the Tioga County facility July 24.

Lockheed officials say the K-Max delivered 4.5 million pounds of cargo and spent more than 2,000 hours in flight.

The chopper is now going to be used for testing and demonstrations but official say they’re willing to hear about other ideas for future use.
