Be carefull here. The dusttrails and/or persistent trains left by meteorites will start to twist after formation due to high altitude winds, often creating a cork-screw pattern in the dust-trail or persistent train. I've seen it happen many times with persistent trains of fireballs. It sometimes happens in seconds. This is not due to the meteorite itself cork-screwing down, but it might lure an eye-witness in thinking it was.
This is not to say that I want to discount the possibility some do, but it is a fact, I have never seen any good photograph of a bright meteor corkscrewing, other than a few where the effect was instrumental (introduced by camera-movements), or likely to be so. - Marco ---------- Drs Marco Langbroek [EMAIL PROTECTED] [EMAIL PROTECTED] http://home.wanadoo.nl/marco.langbroek "What seest thou else In the dark backward and abysm of time?"
