southwest-airlines-737-one-chemtrail9/28/2016 by Patrick Roddie:  An air traffic controller told a Southwest pilot he had “a chemtrail off (his) left wing” last week – and it was recorded for posterity.

40 seconds after Southwest 1256 took off from Portland International at 6:18pm, September 21st, 2016, an air traffic controller in the tower radioed the pilot to say:

“I don’t know if it’s normal I just haven’t seen it that low; it appears like a chemtrail-type situation off your left wing.”

When the pilot asked her to repeat it, she said:

“It looks like a chemtrail off your left wing, I just have not seen it that low before, but it does look similar to a…”

Her transmission is cut off before she can finish the sentence. When you hear her again 10 seconds later, she alters her phrasing to say:

“…alright, a contrail off your left wing.”

The pilot does not appear surprised or concerned.
