"Contrails (short for "condensation trails") or vapour trails are artificial clouds that are the visible trails of condensed water vapour made by the exhaust of aircraft engines. As the hot exhaust gases cool in the surrounding air they may precipitate a cloud of microscopic water droplets. If the air is cold enough, this trail will comprise tiny ice crystals"
Exhaust from the planes hits the atmosphere and leaves a trail, this is just a guess.

Not sure what you are getting at, perhaps the quantity, but I would say they are normal. My personal record is seeing 13 jets in the sky all at the same time.
And this was was caused by a constellation of Angels that conferred with a certain prophet while he was hunting javelins in the Arizona desert in the 1960's. The 7 angels that appeared to him that day gave him the Revelation of the Seven Seals that vindicated him as THE major prophet for this age- and that he was, in fact, the foreunner of the 2nd coming of Christ and that ANY truth to be revealed to the Bride would come through him.
or....
... it was water vapor caused by a test rocket launch at Vandenburg Air Force Base.
