Well, my sister and a friend got dumped on by a plane while in her open jeep, 
now she has MS  and is majorly ill.
  The stuff was sticky and burned, maybe it was crop stuff, but they were in a 
forest area.
   hey jumped into a nearby creek and washed it off the best they could, but it 
didn`t help much.
  Don`t know what the year or place was, I`ll have to ask her.

  I thought I would let this go as you seem ultra high on
  something other than air! :) I have been around aircraft
  for nearly 50 years, and yes I have seen many "vapor" 
  trails plus some UFOs.  I have been fishing out in the Gulf
  at least two days a week, but have not spotted your Chem.
  trails!
