Recall reading a news story a year or so ago about a large chunk of ice that cratered a hole through someone's urban roof that speculation was from a jet airplane. If one of those ice chunks ever falls in your home, just make sure one gets rid of it before it melts if the color is yellow as they are not dumping lemon juice.

Will make a followup input to what I posted at the end of this thread:

Been working on images with Photoshop every evening and have more to go. I actually didn't take my camera out while the big hailstones were on the ground but a bro did so will grab his SD memory card at some point.

Ok, not Sierra but i could see that happening over Yose as well as that is also a major airline highway.


I did in fact consider that the block may have been airliner waste--this was what I initially thought when I saw this thing fall out of the sky. However if you look at photos of the stuff that has reached the ground from planes you see that it recrystallizes as a more solid block of glassy ice (see photo in your feature, for example), as you would expect. In contrast, the big block that fell and fragmented in front of me in Sunol RW was composed of innumerable hailstones stuck together. The photo I attached (late edit) is not too good because this was with my old 1600 x 1200 pixel camera, but I believe it is good enough to see that the internal texture of this ice is very different from frozen airplane waste.
Since my fishing (etc.) website is still down, you can be distracted by geology stuff at: http://www.fresnostate.edu/csm/ees/facu ... ayshi.html
