i was in sunderland this week and we spotted 3 orbital chem trails being sprayed over the city of sunderland at about 2pm on wednesday..ive never seen these before. i have pictures of the 90 degree turn and then they switch off the sprayers, but never a full circle.. it took about 40 mins for 3 planes to create these giant doughnuts..

see my personal page for the pics.. if your interested
