(meteorobs) Meteorobs - skipping meteors

[stange34 at sbcglobal.net]

Hello George.

Interesting thoughts.

I should think that a meteor even if not rotating on its own, would begin a 
rotation from ram-air pressure tending to form a concave bowl which would 
present an uneven larger surface which would then cause a natural rotation 
of the meteor to achieve a lessor surface of ablation. Kinda like taking the 
attitude of least air pressure resistance.

This rotation could promote the ability of a meteor to "skip" if the entry 
angle allowed.......
