I'd guess that a particular "tailwind" is not required to make the situation you describe happen, as it impacts me as a bit too simple. The particles are not falling at the same rate (terminal velocity depends on mass, cross sectional area, their ratio and aerodynamics in general, so differing

Rex and List, That's an interesting point Rex. I have seen that effect. One of my theories about Park Forest had been that it may have been a multi-stage breakup followed by a detonating main mass. Once breakoff pieces separate, they immediately lose energy to the process of seeking aerodynamic

Dear List, To continue our musings on strewnfields, I'd like to firstclarify Adam's post earlier when he identified strewnfields as the fall pattern of meteorites that break upprior toimpact (Park Forest, etc.). This wouldbe fine with me but it suggests we need new/different terminology to
