Cremora Explosion (courtesy of Mythbusters). Almost any fine, flammable material will make a nice fireball if ignited while dispersed. (for example: grain elevator explosions.) Mythbusters, as usual, take it to another level. Bonus: How to make your own. Bonus 2: A million match-heads.

Fire in the sky - a meteor burns up somewhere over Western Canada. Really impressive video here, another video, TV news with more footage here.

Fireballs are not altogether uncommon. They are often associated with known meteor showers (and other times not). They are sometimes "earth crosser" asteroids, cometary debris, or simply man-made space junk. Sometimes they are extremely well documented. The March 7, 2003 Park Forest fireball/meteorite (pdf) was recovered and recorded by police car cameras: (AVIs: 1, 2, 3) Perhaps the most incredible is the one that got away on August 10, 1972. Recorded by many still and movie cameras as it was seen in daylight over the Grand Tetons, it was also recorded by a previously secret satellite during it's 1-1/2 minute skip off the earth's atmosphere.
