Loring, ME - Sphere

3 orbs over Loring AFB

i am filing this on behalf of a deceased friend who confided in me before his death. Sometime in spring/summer 1966 he was an MP at Loring AFB. He was on patrol with another MP and they were at the top of a hill when 3 orange glowing spheres he estimated about 50 feet wide and same in height passed over the base in formation about 30 mph. They followed the spheres until they passed out of view from their jeep. Later that day he was friends with a fighter pilot on the base. The fighter confided that fighters had been scrambled armed with missiles to chase the objects. The pilots tracked the spheres into Greenland where they then shot up at unimaginable speed at a sharp 90 degree angle and out of view in the blink of an eye. The pilot told my friend who was 18 at the time that the pilots were briefed not to mention anything and forced to sign secrecy agreements. I am leaving his name in the contact section. No sounds or exhaust were observed from the spheres and ! no aggressive actions.
