South Carolina, April 12, 2013. Maj. Jeff Beckham performs preflight checks on his F-16 at McEntire Joint National Guard Base. National Guard photo by Jorge Intriago.
Notice what looks like someone spilled a little liquid on the bottom center of the photo, the faint white stream that looks like it is pouring out of the air intake of this jet fighter. I thought it was a little odd; perhaps there is some cryogenic system on board that is venting some gas, and the engine isn't running yet, so it's flowing out and onto the ground. I inquired and got back this reply:
That's the engine intake vortex caused by condensation (water vapor). - IndianatheartReminds me of some pictures of jets with visible vortexs coming off the wing tips.
