Chemtrails - PHOTO OF THE DAY - Non-persistent Contrail in a Chemtrailed Sky

Posted on the 25 April 2013 by Freeplanet @CUST0D1AN
it's about 0920 hours on Thursday 25th April 2013, and here's a lovely example of a 'normal' non-persistent contrail from a commercial jet heading north to south at cruising altitude in a just CHEMTRAILED SKY

in the wider shot, below, the skylong white line indicated from A to B (west to east) has just been laid down, literally FIVE MINUTES AGO as I watched.

both planes were at cruising altitude: explain.
