(meteorobs) Ed, Roberto, et.al., My poorly phrased question on composition....

[Larry]

Chris has already touched on what I also believe is a stoney material 
meteoroid.

What I was most interested in finding out was... whether Chris or anyone 
else knowledgeable could ascertain by the numberous explosions/flares, 
whether Thomas's fireball was a compact stoney (like Basalt), or a porous 
material (like Brecca), or just a stoney with fractures & weaknesses.

My impression given the video light pertabations is that it could be a 
porous object and might be used in the future to identify other truly porous 
fireballs and Bolides.

I have never fully understood the explosion mechanics of a huge ablating 
frontal pressure vs no backpressure and how that governs the actual 
DIRECTIONS of fragmentation in an explosion. In a way....it should blow 
itself inside out but it doesn't. A puzzlement......
