...over London, Ontario, Canada. 



STEVE WRITES: "This attached picture was taken March 25, 1999 over the downtown area of London, Ontario, Canada.  It was a clear sunny day, and we snapped this photo because we had never seen this amount of activity in the skies over London.  Three planes were seen, and one was observed crossing over the city, then turning around to come back over the city for another run. The contrail from this plane can be seen in the lower left portion of the photograph.  It was observed that the plane was not releasing it's contrail all the time - this plane released it's contrail once it got turned around and back on course.  London is a major center for medical research, and does lots of business with American-based biomedical corporations."
