[meteorite-list] Meteoroid/Asteroid Electro-Magnetic Disruption and Charge Properties?

[drtanuki]

Dear List,
If there is anyone willing to discuss the how and why meteoroids/asteroids "detonate" please explain for the list and myself.  I am interested learning more about the electrical/mechanical/physical forces that these bodies undergo as they reach the earth such as in the latest Russian event. Thank you.
