Cutting-edge drone testing is continuing at Griffiss International Airport in Rome.

For the first time today -- NUAIR Allliance -- which runs the UAS test site at Griffiss, flew four unmanned aircraft simultaneously, each flying a complex mission.  NUAIR also flew four drones simultaneously last year, but the aircraft just took off.

Tony Basile, Vice President of Operations at NUAIR, says the testing was done under the watchful eye of NASA, which was monitoring the flights from California.

He says NASA has been tasked with developing an Unmanned Aircraft Systems Traffic Management Program so "the Amazon delivery doesn't run into the pizza delivery."

Basile says today's drone testing was a success.

Griffiss is one of just seven UAS test sites across the country.
