(Chicago Tribune) Many Chicagoans' daily commutes were made extraordinary Thursday morning by a fireball that flashed across the sky shortly after 6 a.m.
In the seconds before the fireball disappeared, WGN-TV helicopter pilot Mike Sypien saw a burning green and red ball of light, which he described as moving faster than an airplane across the sky.
"My photographer was like, 'Holy cow, did you see that?' " Sypien said. "It was very vivid. It was very bright. It almost looked like somebody took a flare and threw it across our windshield."
