The following points can be made by examining the various 15 November 2006 MODIS images and products over southern Wisconsin:

It is felt that the aircraft distrails were formed within a mid-level supercooled cloud deck, causing portions of that cloud layer to glaciate. In addition, a thin veil of higher-altitude cirrus clouds also covered the region, and it was this cirrus cloud layer that showed up as the large area of -30 to -40 C values on the Cloud Top Temperature product and the corresponding extensive area of "ice phase" on the Cloud Phase product.
