I looked up at 20:00 13/07/2010 over west Kent to see this... THIS WAS NOT NORMAL EVEN FOR A CHEMTRAIL,IM NO AVIATOR BUT I'M GUESSING THE CLOUD AT NO MORE THAN 3000 FEET-THE TRAIL IS STILL VERY THIN??? apologies for my shoddy camera skills,I only have a phone cam, I've done 3 passes with different filters to try and highlight the trail,its best visible around the 1 minute mark into each run,much clearer to the naked eye-I'm no video producer but would be grateful for any suggestions on enhancing somehow full music credits to DwoodgreenJ for the music
