May 4, 201115 yr Thought I'd add these pictures to this thread.I was plane spotting today at KPHX, and saw a SWA737 with a relatively unusual (to me, anyway) vortex off its right wing.http://www.flickr.com/photos/russellmjohnston/5685623020/sizes/l/in/photostream/http://www.flickr.com/photos/russellmjohnston/5685053853/sizes/l/in/photostream/It was visible all the way from take off to as far as I could see.Hi there,Well first and foremost she certainly could do with a clean couldnt she?That vapour is most likely formed from the surge tank vent - just a bit of excess fuel and it will quickly stop as the fuel is burned on take off and initial climb out.Hope this helps!Anthony Milner Anthony Milner
