Capt. David Porter, aboard a C-47 military aircraft, spotted 2 objects in formation, about 4 miles apart, and watched them for 7 minutes.
They changed color from red to white, like it might be a heated metal or also like a blinking light.
Their speeds were estimated at 1,500 to 2,000 mph.
One disappeared heading north. The other went straight up.
A B-47 bomber was in the vicinity, but was there an hour later.
