I saw this from the number one google listing from that link and it says on the page
"Why so many photos of contrails in WWII, and not so many from the 50′s and 60′s? The simple reason is that contrails only form at very low temperatures, which are normally found at high altitude, and in peacetime there was NO REASON TO FLY THAT HIGH until the advent of commercial jet travel a few decades later."
Would I see these contrails in low altitude on a day that's say 65 degrees?
