(meteorobs) thoughts, please

[Dale]

pete - thanks for the trouble - it is appreciated

the guy wants to use meteors as just one of many phenomena that he thinks is du to morethan just gravitational force - he advocates EM as being much more of a force in celestial and solarsystem mechanics than is now granted, gravity being virtually the only consideration in orthodox science

of course, i knew meteorITE was wrong, and indeed we know that meteors can 'ricochet' off the atmosphere

what i was really looking for was any evidence that they deviate from their original trajectory as they  either approach earth and/or enter the atmosphere  -- he says 'to the east' -- does that mean regardless of the approach, they turn toward the east?? or did he mean 'to the right'?

no one can answer for what he meant but do we have any evidence about noticeable deviations from approach trajectory, as i phrased it above?

thanks again
dale

  Dale and all,

  Alas, again, no pros seem to be taking on a question for us, so I'll
  give it a try:

  Right off the bat, in number 3, a "meteorite" cannot be repelled into
  space by the atmosphere because a meteorite is defined as having stuck
  the ground.

  Also in 3, I'm not sure what "turned aside" means although there are
  instances when meteoroids have hit the atmosphere and skipped away. The
  daylight fireball in August 1972 (I think that's the year) was filmed
  doing just that.

  >From number 1, most authorities will quote that meteors become visible
  at closer to 100 km rather than to 200 km. At some 125 miles up (roughly
  200 km), there isn't a lot of air to stop anything. "Violent
  displacement" by upper atmosphere winds is not referenced anywhere that
  I've seen. I have no idea whether winds are coming out of the west
  everywhere in the atmosphere, (presumably that's what it would take to
  "displace toward the east") but it doesn't sound right at first blush.
  Is this maybe a reference to diurnal aberration, which is the change in
  the apparent path due to earth's rotation?

  I certainly hope others will tackle this question (and not leave me
  hanging!).
