The trails were traced into south-central Queens County.
Photo shows variety of patterns stretching across sky to the south of observation point.
The sky to the north was clear blue, completely free of clouds and trails. The trails remained in the sky for hours, unlike regular jet contrails which are very thin and dissipate rapidly. These trails spread and merged together. This photo shows trails within trails at the left. This familiar checkerboard pattern has been seen in skies throughout the United States, Europe and Australia.
