the overwhelmingly vast majority of meteorites don't leave any craters in the ground.
What happens when a meteor hits the ground? Usually nothing much, as most meteors are small, and indentations they make are soon eroded away.
Remember in October 2008 when Asteroid 2008 TC3 hit the scene – literally? This was the first asteroid that was predicted –and predicted correctly — to impact the Earth. Luckily, it wasn't big enough to cause any problems, and its path was over a remote area in Africa. It streaked into the skies over northern Sudan in the early morning of October 7, 2008, and then exploded at a high 37 km above the Nubian Desert, before the atmosphere could slow it down. It was believed that the asteroid likely had completely disintegrated into dust. But meteor astronomer Peter Jenniskens thought there might be a chance to recover some of the remains of this truck-sized asteroid. And he was right.
Fifteen fresh-looking meteorites with a total mass of 563 g were recovered by 45 students and staff of the University of Khartoum during a field campaign on December 5-8, 2008. A second search on December 25-30 with 72 participants raised the total to 47 meteorites and 3.95 kg. Masses range from 1.5 g to 283 g, spread for 29km along the approach path in a manner expected for debris from 2008 TC3

Considering that Jim Oberg as already posted on this thread I think you can him for a clarification, I am sure he doesn't mind answering your questions.

The fireball was observed by many people in Ontario, Michigan, Ohio, Pennsylvania, and to a lesser extent in neigboring states. In newspaper accounts, a great many supposed impact sites were reported, both in southwestern Pennsylvania and eastern Ohio. Fragments were claimed to have fallen in Ohio and Michigan.
These imagined happenings arose from the impossibility of estimating the distance of an object in the sky. Almost everyone who saw the fireball thought it was much closer than it really was. When it disappeared behind a house or a tree many people thought it had fallen only a few hundred yards beyond.

If this is your option 5 it totally ignores photographic and eye witness evidence.
Are you saying that we have a meteor that left that smoke trail - as that has been traingulated and wasn't hundereds of miles away ?

However what they've done in this report essentially was to extrapolate a trajectory from pictures of the fireball taken in Michigan, and using an assumed velocity they calculated an approximate orbit of the assumed meteorite.
"A puff of smoke was visible at the terminal end of the train, where reports indicated the major burst occurred. The visible fireball ended at this point, but several observers reported that some material apparently continued beyond, along the original trajectory. This was subsequently confirmed by the photographs (figure 1)"

I wouldn't say the trajectory is extrapolated. Extrapolation refers to a projection of known data. That's not what they did (except for the orbit calculation, but the big unknown in the orbit calculation is the exact velocity which they can't calculate from photos).
They triangulated known data and identified 2 data points on the ACTUAL trajectory (not any extrapolated trajectory).

Note I said I was only 99% certain no fragments made it to Kecksburg, but if the 1% chance happened and a fragment 32 kilometers high managed to make a right angle turn from northeast to southeast and travel 528 kilometers in the direction of Kecksburg before hitting the ground, then I would expect that fragment to be something like this:

They do seem to consider it a meteor but the explosion at 32km high is quite consistent with the 2008 asteroid explosion at 37km high, and the explosion is well documented in the photos, so we have to consider that they may be right about it being a meteor.

Excellent research - star for you.
Forgive me for perhaps being a bit slow but I still do not see what you are trying to say.
Is it that the eye witness reports, local fires and other accounts refer to a meteorite that disintegrated hundreds of miles away but subsequently a totally unrelated large object was found locally ?
Or that two events happened, the meteorite and the coming to earth of a large object, possibly of russian manuafacture ?
I accept and applaud if you do not have a coherent theory currently and are just researching but there must be a particular direction you are heading ?

You mean these witnesses who identified the object as looking just like a Russian Satellite?
Which confirms the NASA statement it was a Russian satellite?
I don't know what happened that day. But I can't rule out the possibility that a Russian satellite landed in Kecksburg at 6:20am, then a meteor fell a hundred miles or more from Kecksburg at 4:45pm, and the witnesses who saw the meteor went looking for the fallen object thinking it was much closer, and found the Russian satellite, called up some officials, and the officials came to recover it. Your 4 options are not the only possibilities.
Something else could have fallen in Kecksburg that day. But I guess I place less credibility on witness testimony than some because I have read a lot of research about how unreliable witness testimony is. It's very unreliable, and in this case, we even have some witnesses saying that nothing happened in Kecksburg that afternoon. If witnesses are so credible, should we believe them? No? OK then you agree also that some witnesses are not reliable!

The explosion (instead of being a meteor breaking up upon re-entry) signified a major problem in the craft, and after the explosion, the craft managed to make a right angle turn, coming down in Kecksburg, as opposed to Michigan (as it's earlier descent indicated) and made a semi-controlled landing.
