You See it on the concorde's wings after takeoffhttp://www.airliners.net/open.file/224801/L/It's right there on top of the wings

:-(

The link failed but I suspicion what you are viewing is the condensation created by the low pressure on the upper surface of the wing at high humidity levels. Being rather inexperienced in these matters, I would surmise that the direction to take is to link an effect to a low speed on that particular aircraft.

Hey James,I think there are some jet fighters (Kirk's F-16?) out now that have this effect. Check that and maybe the DSB Typhoon. Not sure, but I know I have seen it. Hope this helps.
