But it's not aliens
If you're in Guilderland Thursday and see a number of drones in the sky, New York State Police say don't be alarmed. Agencies from around the area will be conducting drone training at the State Police range near Grant Hill Road.
Part of the training will include night flying, which means you could see some mysterious lights in the sky in the evening hours.
Police are asking any drone hobbyists not to fly near the area between the hours of noon and 8pm.
