Show them your RadarBox and point out that when aircraft follow a fixed airway, any crosswind will blow the contrails to the side - if the planes are regularly spaced, stripes appear. Often get that round here.

Either that or it's Ryanair trying to kill off potential Easyjet customers ;-)

A few years ago, we had a few of these conspiracy theorists using RadarBoxes to prove that these chem trail jets actually turned off there transponders so they cannot be tracked.

However they just showed some aircraft which didn't have ADS-B transponders :) but this would have easily confused anyone not knowing about Mode -S and ADS-B.

Fred - it's all down to the weather and time pf day - the temperature and humidity of the air the planes are flying through, and whether there's much turbulence up there, which would cause the contrails to break up quicker.

In the future when synthetic fuels come into use, I supose that may effect the contrails for better or worse.
