yes, I noted the same.
The tiles have lower density and if any survived to the ground (which I doubt) they should be "earlier" in the ground track.

The tiles would be laying in California's forests of the Sierras or in the deserts of California-Nevada-Arizona. Finding a 2 inch tile remnant in that huge desert seems improbable.

Finding a crater from a aluminum or steel object going 200 mph seems far more likely.

I wonder if citizens could be used to scan the area east of Tonopah for the object seen by astronomers in California.

It seems a daunting task, but worthy of the effort. I wonder if NASA will reach the same conclusion/s and be motivated to look for clues uprange ? I appreciate your effort in cranking out the math calculations.

NASA stated that they had scoured around 70% of one significant wide ranging debris field and 80% of another in Texas. I was surprised to see the percentage as high as it was.
