The one time I saw a true fireball was during the Orionids my Sr. year of HS. My girlfriend lived on a ridge out in the country, it was an unseasonably warm night for late October, we were in the back of my truck cuddled up and enjoying the skies after midnight when one came across the sky with a shower of sparks making a crackling noise. (It was dead quiet out there.)
I tried to convince her it was sign that we should be doing something else than cuddling, but she wasn't buying it. That's what I get for dating the class valedictorian.
That was an interesting four years of HS, I got to witness two rare phenomena, the Fireball of Lick Creek, and ball lightning while waiting for the bus home on a humid, getting ready storm afternoon. The later the damnedest thing I ever saw, in both it's behavior and the effects it had on the kids who saw it, about 20 of us. We were all looking at after someone mentioned seeing an odd speck of light across the valley. It came closer and closer, changing in both size and color, primarily a combo of of orange, red, and yellow.
It came close to ground about 30 yards away, about the size of a soccer ball and flat, moving a little over walking speed, in an up and down sine wave, changing shapes and colors as it cut across a section of street at about a 75% horizontal angle, passing by us by about two yards away, by this time, now the size of a beach ball but two dimensional, again it looked like a flat disc. It went past us for another ten yards and passed behind a stand of small, but dense hemlocks. Not less than five seconds after going behind those trees, it gave out a loud boom, which startled us out out trying to comprehend what happened.
A few of us ran around the side to see what happened, as the teachers parking lot was behind those trees. I think we were all hoping it had blown enough their cars sky-high, we get to skip the last week of school. No such luck, not a scorch mark on the ground, the branches on the trees were fine, as were the cars, drat!
What was so odd was of the kids who had witnessed it, a solid third of them couldn't remember a thing about it the next day?
